Alpha Silicone® Liners

Print

Now available in small sizes!

WillowWood’s Alpha Silicone Liner uses a proprietary, platinum-cured, medical grade silicone designed for comfort and performance. Our unique blend of silicone, Vitamin E, and skin conditioners results in a pleasing surface that is non-greasy, non-tacky, and comfortable against the skin. The Alpha Silicone Liner uses Select fabric that controls pistoning without using a distal matrix. The Select fabric allows for circumferential stretch making it easy to don for numerous limb shapes. The flexible knee panel provides enhanced knee flexion and a broad range of knee motion.  The Alpha Silicone Liner may be retrofit with Alpha Classic® LIner and Alpha Hybrid® Liner that has a progressive profile.

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.
