Easy-Off®   Lock

Why the Easy-Off® Lock?

Our newest, robust Easy-Off Lock design is here and better than ever. 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, pin lock system

  • Great for amputees with hand strength issues

  • Single-stage lamination

  • Offset alignment capability

  • O-ring system for positive seal

Which Pin to Choose?

Locking Lanyard

Airtight, water-resistant lanyard lock

  • The lanyard pin helps elongate the limb when donning

Single Lamination & Offset Fabrication

The fabrication procedure for the 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 set up. 

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 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 can be billed when using dual suspension. Not recommended for billing with Medicare.
