Coyote Design's prosthetic locks are made to stand up to the elements so you can participate in whatever life brings.


Made in USA

Simply easier. Designed to control rotation and be more user-friendly, the Proximal Lock attaches over a larger area, which distributes weight more evenly. The adhesive included with each lock is flexible even after it sets, making donning simpler.


The CD101 Summit Lock, and CD102 LowPro Summit Lock are still available, however because of the improved liner attachment, and easier-to-use glue, we strongly suggest using the Proximal Lock instead.

CD116 |  Proximal Lock

Includes liner attachment, lock,

fabrication dummy, glue form,

and adhesive.

Patent No. 6666894, 7431738, 7077868.

Other patents pending.



The glue form for the Proximal Lock features a guide hole and locater indents to help ensure that the liner attachment is glued in the correct location.

Silicone liner attachment helps with easy doning. It also helps seal the exit hole for the tab.

Lock is easy to don, can be attached with a provided fabrication dummy or can retrofit on an existing socket.

The Tab creates a simple visual locking mechanism working well for all activity levals including geriatric, pediatric or people who need assistance doning and doffing their prosthetic.

Billing   The Proximal Lock will bill just like a distal pin lock system (L5671). Gluing the lock to the liner turns the Proximal Lock from a cushion liner to a locking liner (L5673).

Improved Suspension   We recommend adding an expulsion valve to most sockets that use the Proximal Lock. This helps with donning and will evacuate the maximum amount of air from the socket which improves suspension and reduces pistoning.

Limb Type   The Proximal Lock was designed to work with long limbs and can be the primary suspension for patients who may not have room distally for other lock options. The Proximal Lock can be used for short limbs only with a distal pin; in this case, the Proximal Lock will act only as rotational control.

Retrofitting   The lock can be retrofitted to an existing socket or put on the outside of a test socket.

Test Socket   Initial fitting of the socket should be done without the lock. For extended test periods the lock can be retrofit to the socket.

Recommended Codes


L5679*   Addition to lower extremity, Below Knee/Above Knee, custom fabricated from existing mold or prefabricated, socket insert, silicone gel, elastomeric or equal, for use with locking mechanism.


*Adding the Proximal Lock to a cushion liner changes the liner from a cushion liner to a locking liner. So we recommend billing L5679 instead of L5673.
