Alpha® Lock

The contoured design allows for easy pin alignment within the locking mechanism. The Alpha Lock has a built-in one-way expulsion air valve which minimizes pistoning. Available with or without a titanium pyramid. The Alpha Lock is part of the Alpha Interlock™ Suspension System. This system allows you to interchange suspension methods without remaking a socket. The Alpha Lock may be used in laminated or thermoplastic sockets.

    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.
