Alpha® Classic AK Liner
Now available in two profiles
Alpha Classic AK Liners are available with our AK Profile or our Symmetrical Profile. Alpha Classic AK Liners are heat moldable, allowing prosthetists to easily stretch the liners.
Classic AK Liners with the AK Profile accommodate the often sensitive areas of transfemoral residual limbs with a specific gel style and the incorporation of skin-friendly, mineral-oil-based classic Alpha Classic Gel. The liner, offered in cushion and locking, has 9 mm of gel distally, tapering to 3 mm proximally—with a built-in gel pad to protect the often-sensitive femur. This extra gel pad provides a total of 9 mm of gel at the distal lateral aspect of each liner. The Alpha Spirit Fabric used for Alpha Classic AK Cushion Liners is unique in its ability to flex during donning or doffing. Alpha Classic AK Cushion Liners may be used with a Velcro®-like material for added security.
Liners with the Symmetrical Profile have 9 mm gel distally and taper to 2.5 mm gel at the anterior and posterior. The symmetrical design allows the liner to be rotated for extended wear. This profile is a good choice for amputees who reflect liners for greater comfort at the socket brim line. The Select Fabric, only offered with the Symmetrical Profile, is a one-way stretch fabric that controls pistoning yet remains easy to don.

L5673 Locking Liner (bill once per liner)For locking liners, 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.
