WillowWood® Express AK Liner


WillowWood’s Express AK Liner is a softer-durometer silicone that replicates the feel and comfort of TPE gel liners. The platinum-cured, medical-grade silicone contains skin-friendly Vitamin E to foster a healthy limb environment. And true to WillowWood form, no messy lotions or creams are necessary to don the liner. WillowWood Express AK Cushion Liners use Spirit or Select fabric while the WillowWood Express AK Locking Liners use the Select fabric or the one-way stretch MAX fabric.

The specifics for this liner are: AK Profile and fabric colors of either buff or dark gray. Size offering is limited to Large Plus only. WillowWood Express Liners may have a lead time of up to 10 days. Ask about availability when ordering.

Please note that drying stands are not included with Alpha Liners. Available separately in most countries.

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.
