Alpha® DUO Fabricless Symmetrical Liner

The fabric-free outer Alpha Duo Liner combines the comfort of gel with the durability of silicone. Alpha Classic gel lines the interior, providing all-day comfort with skin-protecting mineral oils and vitamin E. Alpha Silicone covers the exterior, providing durability and protection with a satin finish for easy donning.

A One Gel Sock is included with each Alpha Duo Liner, which aids liner longevity and provides an air wick for optimal suction and vacuum suspension. This sock can be cut to match the trim line of the socket, improving knee flexion.

This liner can be combined with the movable One Seal to create a seal-in suction option for both AK and BK sockets – allowing the optimal seal location to be used.

Description

Symmetrical Profile

The symmetrical profile has increased thickness distally to provide increased comfort and protection. This tapers to 4.5mm proximally for easy donning, and a thinner edge when cutting. Being uniform circumferentially means that it can be rotated by the user to increase its lifespan.

  • 9mm distal end
  • Thins to 4.5mm proximally
  • Uniform circumferentially

Fabric-less

Alpha fabric-less liners were developed for use with the One system. However, they can also be combined with the One seal and One sock for a seal-in solution.
