Achieve the security of a pin while minimizing pistoning through the use of suction.

Many of the locks offered by WillowWood incorporate a one-way expulsion valve or pin seal to provide amputees with more security and a comfortable fit.  Each of our locks are designed with the ease of fabrication in mind.  Our Alpha Interlock® Suspension system allows you to switch from locking to suction without having to make a new socket.
