Alpha® Lamination Lock


The Alpha Lamination Lock is small in size, light in weight, and can be used in either a one-step or a two-step lamination. With the incorporation of an attachment plate in a two-step lamination, various angle options can be utilized to optimize foot alignment instead of allowing the shuttle lock to dictate alignment. The Alpha Lamination Lock adapts to all six Alpha Locking Liner sizes — from small to extra-large. An airtight fit is achieved with the inclusion of a pin seal, which seals off the socket. One pin is included with each lock.

WillowWood strongly recommends applying Loc-Tite Removable Threadlocker 242 (or equivalent) to the pin threads prior to installing the pin. Failure to ensure that the locking pin is secure in the Locking Liner could result in the pin coming out of the liner, resulting in the potential for injury to the amputee.
