Easy-Off Lock™

New robust Easy-Off Lock design. Very similar to the Air-Lock in that it stays airtight to create suction in the socket, the Easy-Off Lock can be used with elevated vacuum. Its unique lever design also makes doffing easy, especially for amputees with hand strength issues, arthritis or trouble reaching the release button.

  • More robust lever design
  • Airtight “suction” or vacuum suspension with the safety and security of a pin
  • Easy donning and doffing with lever release
  • Self-lubricating materials reduce wear
  • Water-resistant
  • Can be used with elevated vacuum
  • Dual suspension, suction pin lock system
  • Great for amputees with hand strength issues
  • Single-stage lamination
  • Offset alignment capability
  • O-ring system for positive seal

  • – The lanyard pin helps elongate the limb when donning.
  • – The pin gives audible confidence of engagement.
  • – The o-ring at the end of the pin creates an airtight socket helping to reduce air noise.

Same simple fabrication as the Deep Air-Lock

and Deep Easy-Off Lock pin systems.

It is recommended to use the Deep Air-Lock or Deep Easy-Off Lock with the Locking Lanyard Pin.

Billing Information

Recommended Codes

L5671   Addition to lower extremity, Below Knee/Above Knee suspension locking mechanism (shuttle, lanyard or equal), excludes socket insert.

L5647*    Addition to lower extremity, Below Knee, suction socket.

L5652*   Addition to lower extremity, suction suspension, Above Knee or Knee Disarticulation Socket.

*Not recommended for billing Medicare. Coyote® believes that “suction” in a prosthetic refers to the negative pressure created inside the socket, rather than componentry such as an expulsion valve or sleeve. Because we think of suction as a function, we believe it should be permitted to bill L5671 in conjunction with the L5647 or L5652 in cases when it is medically necessary. As with other situations where multiple suspension methods are used and billed we feel the combination of a lock and suction helps to increase safety for the patient.

**The CD117 Easy-Off Lock can be used with a vacuum system and will maintain vacuum levels. Both lock code and vacuum code can be billed when using dual suspension. Not recommended for billing with Medicare.

For more information on billing the Air-Lock and on our socket pressure study between airtight and traditional pins contact Coyote.

The listing of codes with our products should not be construed as a guarantee for coverage or payment.

The ultimate responsibility for the coding of services/products rests with the individual practitioner.

Single Lamination and Offset Fabrication

The fabrication procedure for the Air-Lock and Easy-Off Lock is a time and money saver. The Alignable Connector is attached to the lock in the desired location for prosthetic alignment, allowing the lock to remain in ideal lock alignment for easy engagement. A single lamination is done that incorporates the lock and the connector into the socket. The offset capability saves money by eliminating the need for offset components and saves time with a single lamination and easy component setup.
