Frequently Asked Questions

You will need to order the following components: 1) A package of pins 2) A lock wrench 3) A connector (Alignable connector or a One-Shot Connector) 4) An Insert (Single directional or Multi directional)

We recommend using either Co-Poly, Vivak, or MPE for your check socket.

Yes, the Air-Lock is water-resistant. We recommend rinsing the lock and components when used in saltwater, chlorine, or in an environment that contains dirt, sand, and grit. See our video here on Patient Maintenance instructions. *NOTE: A prosthetist may need to remove the lock mechanism and blow out the lock housing with an air hose.

There is no need to use a suspension sleeve with the Air-Lock, as long as you have a full contact socket. When you fabricate with the Air-Lock, you are sealing off the bottom of the socket. No air is getting in from the bottom of the socket, creating suction in the socket. Air will still wick around the top of the socket, but it’s not being ‘forced’ into the socket meaning that the socket stays airtight. *NOTE: If you opt to use a sleeve, an expulsion valve is needed.

Any liner that accepts a 10mm pin (6mm pins are also available). Fabric or Non-Fabric Backed liners both work well.

L5671, *L5647, and *L5652 *NOTE: The billing codes listed should not be construed as a guarantee for coverage or payment. Ultimate responsibility for the coding of products/services rests with the individual practitioner. *L5647 and L5652 are not recommended for billing Medicare.

The Air-Lock will not hold the pressure of vacuum, because the release button will get sucked in actually release the pin The Easy-Off Lock has a unique lever release and is the only lock that can hold the ‘pressure’ of vacuum.

A “whooshing” noise means the socket may not be properly sealed at the bottom because there is a gap between the top of the valve body and the top of the funnel allowing air to flow into the socket. To test this, run some water through the socket to see where it is leaking. If that is the issue simply seal off the inside of the socket where the outer circle of the lock touches the socket. Adding a CQL Auto Expulsion Valve to the socket may also help. A squeaking or clicking noise that repeats with every step, means the alignment may be off with the socket. You may need to add or remove spacers. If the patient is wearing socks, the metal end of the liner may be too long for the recess in the lock and it will ride on the inside of the lock and make the squeaking noise. To Fix: Try using a brass pin or put a P-Lite donut on the end of the liner

Our company determined the Housing O-Ring was not needed; the part is discontinued and not packaged with the Air-Lock.

Yes, you can grind the release button to shorten it to the desired length. *NOTE: It’s important that you leave at least up to ¼” inch remaining above the edge of the valve body to still ensure functionality.

There is a Release Button Cover (CD103RBC) available that can be glued on with a gel-type super glue that provides a larger area for the patient’s hand to push for release. *NOTE-Do not shorten the Release Button less than 7/16” in length if you want to attach the Release Button Cover. If the release button was shortened too much, they can be replaced.

For the Air-Lock: 8 Click Pins: CD103P8 (two part pin) or CD103P8H (solid brass) For the DEEP Air-Lock: 11 Click Pins CD103P11 (two part pin) or CD103P11H (solid brass) *NOTE: 11-click pins should ONLY be used with the Deep Air Lock. Parts are available to modify locks in existing sockets if the pin is bottoming out in the lock. To modify the lock you will need the Guide Pin (CD103GPN) and Pin Cap (CD103PC) and Coyote QUIK Glue. Also: Loctite Blue 242 must be used on lock pin threads after determining the appropriate lock pin spacing.

Yes, Drop-In Air-Locks are now available for the Air-Lock CD122A and the Easy-Off Lock CD122E *NOTE: The lamination dummy is a separate purchase: Drop-In Air-Lock Fabrication Dummy part #: CD122AFD Drop-In Easy-Off Fabrication Dummy part #: CD122EFD

If you need a ¼ x 20 thread, please order part #: CD103PQ If you need a 6mm thread, please order part #: CD103PX

Our locks are rated and tested up to 265 lbs. Contact our office for any questions. *NOTE: The strength is in the lamination, not just reliant on the lock component.

Yes, it is fine to use a Keasy Cone.

First, please ensure that the lock alignment is where it should be and/or the liner is being rolled on the way it should. A long pin might be needed. In extreme cases the Locking Lanyard (part #: CD103L) may be the best option for this type of patient/situation. The lanyard pin helps to elongate the limb when donning, making it easier for the patient to engage.

The first things to ask and analyze are the following: What liner, what socks, and what pin spacers are being used? Sometimes the liner bottoms out on the inner part of the lock funnel rather than outer. This can be confirmed by putting a P-Lite donut on bottom of liner when engaging. The brass pin can also be tried. You can also look for marks on the lock funnel.

The odds are very low in normal day-to-day activities that would cause the release button to be ‘bumped’ and cause the pin to disengage. The suction aspect of the lock helps reduce the risk even further. However, activities such as horseback riding, or motorcycle riding do present scenarios where it may be possible that the pin could disengage. If this is a serious concern the practitioner may consider using an Easy-Off Lock (CD117) instead of the Air-Lock.

The best lock we have for this and similar activity levels would be the Easy-Off Lock (CD117). The lever release is different, and you wouldn’t need to worry about ‘bumping’ it. *NOTE: You could still use the Air-Lock (CD103) and you can fabricate a deep recessed button using the Exo Lamination Plug (CD103ELD). You can find more info on our website here. Another option would be to cap the button with the Release Button Cover (CD103RBC). The Air-Lock is hard to release, and it’s easy to build up around the button to further prevent this, and or done in the lamination with the Exo Lamination Plug.

The brass pin is stronger, and better for higher activity patients or heavy-duty patients. It is also corrosion resistant.

In a new lamination, it is worth checking the lock housing for resin, sometimes that will leak into the lock and you end up with a thin layer of resin that causes issues. Because of the anchor, it is really thin and can be unnoticed. A squeaking or clicking noise that repeats with every step, means you may need to add or remove spacers. If the patient is wearing socks, the metal end of the liner may be too long for the recess in the lock and it will ride on the inside of the lock and make the squeaking noise. Try using a brass pin or put a P-Lite donut on the end of the liner or use a “Fitting Lock” to adjust spacers. Other things to check on the lock level include: lock condition, pin condition, check liner in hand, and pull to check. *NOTE: If those options don’t work, you could try a ‘Bench Load Test’: Hold the posterior wall of the socket in one hand and hold the foot in the other hand. Then try to move in a posterior-anterior rocking motion to emulate the walking motion. Check every component to make sure all screws are tightened, including set screws and any metal touching metal.

We never put any lubricant anywhere near the lock, as that will eventually just attract more debris and dirt which wears out the lock faster. This is a good time to put a P-Lite donut on the liner to see if that helps reduce the noise. The noise may be from the liner rubbing against the socket. Rough up the liner a bit where it connects to the socket. If neither of the above works, try the brass pin.

Once the air is expelled there should not be an issue to prevent air from entering again.

Yes, do the blister molding with the lock in place, then glue the connector on and buildup from the lock down to the connector and then wrap the perimeter/outside to strengthen the mold in place.

You can use Quick Glue to fill in the gap.

We have two holes in our vacuum station one for the inner bag and one for the outer bag. Here is a video made by one of our technicians about our vacuum stations. https://youtu.be/gErK55QVp-w

The Low Profile Lock bills the same as a distal pin lock system – L5671. By gluing the lock to the liner, it turns a cushion liner into a locking liner L5673. *NOTE: The billing codes listed should not be construed as a guarantee for coverage or payment. Ultimate responsibility for the coding of products/services rests with the individual practitioner.

NO, it cannot be retrofit. If needed, to identify placement for the Low Profile Summit Lock, you can use a Summit Lock to find the correct placement on a test socket and move it if necessary. Then on a laminated definitive socket you can use the Low Profile Summit Lock to reduce build height of the lock.

At least one (1) hour, but we suggest letting it set overnight.

Any Five (5) minute epoxy will work. *NOTE: DO NOT USE SILICONE BASED ADHESIVE

Co-Poly, Vikvak or MPE

Yes, the Low-Pro Summit Lock is water-resistant. We do highly recommend rinsing the lock and components when used in saltwater, chlorine, or an environment with dirt, sand, grit

The liner MUST be fabric backed for good adhesion.

At least one (1) hour, but we suggest overnight.

Yes, the Summit Lock is water-resistant. We recommend rinsing the lock and components when used in saltwater, chlorine, or an environment with dirt, sand, grit.

The liner MUST be fabric backed for good adhesion.

The Summit Lock bills the same as a distal pin lock system – L5671. By gluing the lock to the liner, it turns a cushion liner into a locking liner L5673. *NOTE: The billing codes listed should not be construed as a guarantee for coverage or payment. The ultimate responsibility for the coding of products/services rests with the individual practitioner.

Yes, it can be retrofit.

First, grind away any excess glue on the lock and liner. Use acetone to get those areas cleaned up very well. Make sure to remove any silicone that appears to have been used. Finally, make sure that you use Quik Glue or another Urethane based adhesive to attach the Summit Lock. If wrong glue has been used, you probably will need a new attachment. Stick the attachment down quickly before glue starts to gel.

At least one (1) hour, but we suggest overnight.

Yes, the Silicone Adhesive comes with the Lock and is enough adhesive for two (2) liner attachment applications. *NOTE: If the patient wants a second liner with attachment, you will only need to purchase the Extra Strap Kit (CD116XS). If used properly, you should have enough adhesive that came with the lock.

NO - Only use Silicone Adhesive (Coyote Part # CD116SA)

Co-Poly, Vivak or MPE.

The liner MUST be fabric backed for good adhesion AND it is best if the liner only stretches horizontally.

The Proximal Lock bills the same as a distal pin lock system – L5671. By gluing the lock to the liner, it turns a cushion liner into a locking liner L5673. *NOTE: The billing codes listed should not be construed as a guarantee for coverage or payment. Ultimate responsibility for the coding of products/services rests with the individual practitioner.

Delamination of a liner fabrication happens when the fabric doesn’t hold up well or the strap is being pulled way too hard, or both.

The reinforcement strip/pad is optional but will help add strength and create less friction between the strap and the liner attachment when donning/doffing.

The reinforcement strip is placed on the outside of the liner attachment – it is not attached to the liner.

In this case the socket could be too loose. We recommend to put a pad like a P-Lite pad inside the socket where the bolt is to help push it out.

Yes, the Proximal Lock is water-resistant. We recommend rinsing the lock and components when used in salt water, chlorine or an environment with dirt, sand, grit.

No, it is built into the socket and it canNOT be retrofit.

You can try by using Acetone to remove and clean the area on the liner but there is no guarantee you can effectively reset the attachment. *NOTE: DO NOT scuff liner!

Yes you can. Please order part number CD116LA – Proximal Lock Pad (Liner Attachment)

If the lamination is too thick you will have to sand it down a bit until the screws will fit. It is very difficult, if not impossible, to find screws to replace that are longer so sanding down the area to fit the screws is highly suggested.

In this specific case, we recommend using the Summit Lock (CD101) because it easy to retrofit and would work best. However, adding the Summit Lock won’t necessarily address or solve the air issue but may help to expel air once the patient gets up and starts walking. It is critical to make sure that the Summit Lock is above the seal band. Finally, you may want to take a look at our CQL Auto Expulsion Valve (CD105) as an option for the patient.

The pin selection will depend on the liner. Most liners are 10mm – use the CD104P10 Ossur Upper Extremity is 6mm – use CD104P6 WillowWood P Pod is 1/4×20 – use CD104PQ

L5671, *L5647 and *L5652 *NOTE: The billing codes listed should not be construed as a guarantee for coverage or payment. Ultimate responsibility for the coding of products/services rests with the individual practitioner. *L5647 and L5652 are not recommended for billing Medicare.

Fabric or no-fabric backed liners both work well with the Grommet Lock. *NOTE: Please make sure you purchase the correct pin depending on if the liner has a 6mm, 10mm, or 1/4x20mm thread.

No, you can also use the Small Air-Lock. The Grommet Lock is best for pediatric patients or low activity adults. The Small Air-Lock is great for Upper Extremities in adults and patients that are physically active with their upper extremities or may be lifting heavier weight.

3” or 4”

4”, 5”, 6”, and 7”

This depends on the amount of vacuum you use. Epoxy resin can take 20+ lbs. of vacuum and not fray on the edges. For Acrylic Modified Epoxy, use 10-14 lbs. of vacuum in the lamination process.

Use equal amounts of Coyote Composite in place of carbon fiber in your existing layups or you can try one of Coyote’s sample Layups

Layups are affected by the type of resin that are used. Modified Acrylic is thinner, easier to saturate and fast to cure Epoxy Resin; is stronger, clearer, thicker with a slower cure time – Epoxy works well for heavier more active patients

We suggest that you use a Fitting Lock to adjust the spacers correctly to ensure the pin is not riding on the bottom of the lock or riding on the inside of the lock. *NOTE: NEVER use a Fitting Lock in a Test or Definitive socket – Their only purpose is for pin adjustments to achieve proper seating.

The brass pins were introduced to help with strength, wear characteristics, and to help with a ‘squeak’ that some patients will notice with plastic pins. They are stronger, easier to service, and corrosion-resistant.

A Locking Lanyard is primarily used for Above Knee (AK) patients due to residual skin/flesh. the Lanyard pin helps elongate the limb when donning.

The Lanyard Pin is used only with the Deep Air-Lock or the Deep Easy-Off Lock. They have different part numbers to ensure you get the pin with cable attached: Air-Lock Locking Lanyard with pin (Part #CD103L) Easy-Off Lock Locking Lanyard with pin (Part#CD117L)

You would order and attach the Lanyard Pinch Disk (CD118PD); The residual cable string is wrapped around the disk and held in place and out of the way.

Co-Poly, Vivak or MPE.

Yes, the Easy-Off Lock is water-resistant. We do recommend rinsing the lock and components when used in saltwater, chlorine or an environment with dirt, sand, grit. *NOTE– A prosthetist may need to remove the lock mechanism and blow out the lock housing with an air hose.

Any liner that accepts a 10mm pin (6mm pins are also available). Fabric or Non-Fabric backed liners both work well.

L5671, *L5647, and *L5652 *NOTE: The billing codes listed should not be construed as a guarantee for coverage or payment. Ultimate responsibility for the coding of products/services rests with the individual practitioner. *L5647 and L5652 are not recommended for billing Medicare.

For the Easy-Off Lock: 8 Click Pins: CD103P8 or CD103P8H (solid brass) For the DEEP Easy –Off Lock: 11 Click Pins CD103P11 or CD103P11H (solid brass) *NOTE: 11-click pins should ONLY be used with the Deep Air Lock; Parts are available to modify locks in existing sockets if the pin is bottoming out in the lock. To modify lock you will need the Guide Pin (CD103GPN) and Pin Cap (CD103PC) and Coyote QUIK Glue. Loctite Blue 242 must be used on lock pin threads after determining the appropriate lock pin spacing.

Yes, this part number is CD117LP and is known as the lock plate assembly. It is all one piece with the lock tooth, springs, and comes with four (4) replacement screws.

No, the Easy-Off Lock replaced the Suction Lock – We no longer offer the Suction Lock or its parts/pins.

Our locks are rated and tested up to 265 lbs.

A suspension sleeve can help control socket rotation and can always be used as a secondary form of suspension. If used with an Easy-Off Lock, it can hold vacuum in the socket if dual suspension is used, and will hold suction if used with either the Easy-Off or Air-Locks (in this case, it is recommended to add a valve to the socket as well).

Valves can be used for suction.

The HandsFree Valve offers auto expulsion for easy donning but adds a twist to open airflow for easier doffing. The CQL valve only expels air. Both valves can be used with elevated vacuum.

Please use the following: Below Knee (BK) use either the CQL (CD105)

Once you take the valve apart with the lock wrench and its fairly simple to clean. There is a small filter in the CQL to catch dirt and debris. The durability and longevity have been good, and it’s easy to retrofit into a socket if you need to add one later.

Yes, they are made of Aluminum, however the screws in the connector may rust if exposed to saltwater. Therefore, we recommend that you always rinse after exposure to saltwater.

No, the connectors do not need to be used with inserts, they can be glued to the lock with any offset position. However, using the inserts can allow the connector to be keyed onto the bottom of the lock in different offset positions.

The One Shot Connector is for the Definitive Socket ONLY (Part #CD111) The Alignable Connector can be used for both the Check- and Definitive Sockets (Part #CDC103AF)

The One Shot Connector is .500 in build height versus .625 for the Alignable Connector.

The Test Socket Connector (CD119SC) is made of PVC and is inexpensive and reusable. They are designed specifically to glue a connector to a Vivac Test Socket. The Test Socket Connect must be “roughed/scuffed” prior to each use for good bonding.

There are currently three flexibility options, and they are easy to replace if you decide to try different options: Extra Soft Flex Kit (CD207XS) for light to medium activity levels or heavier weight-low activity patients (weight range: 70-150lbs Soft Flex Kit (CD207S) for light to medium activity levels or heavier weight-low activity patients (weight range: 90-200lbs Medium Flex (CD207M) for light to medium activity levels or heavier weight-low activity patients (weight range: 125-200lbs). Rigid Flex (CD207R) Patient Weight Range: 200-280 lbs. Patient Activity Level: Light to Medium Activity Level Extra Rigid Flex (CD207XR) Patient Weight Range: 260 – 350 lbs. Patient Activity Level: Light to Medium Activity Level There is a Fitting Kit available at a highly discounted price so a clinic can have different flexes to try on a patient. There will be more strut options coming out in the future so please watch out for them.

Yes, the strut can be cut with a saw and sanded and buffed to smooth and finish the cut edge.

Yes, our AFO Struts were designed, manufactured, and tested in house, with over one (1) year of patient testing
