Rubber Diaphragm is expandable to accommodate any leg /cast size, forms a watertight seal around the arm. Simple and easy pull-on application is user-friendly, there is no need for tapes or straps to secure.
The rigid ring holds the diaphragmand offers a self-sealing mechanism. It is easy to clean maintain, wear, and remove.
A transparent flexible body is non-porous, watertight, soft, flexible, lightweight, and durable with pleasing aesthetics. It comfortably houses the arm/cast.
Tynor Cast cover is made from a durable, transparent PVC fabric. It covers the limb when applied and the sealing is done with an expandable hole drilled into a latex diaphragm which is held in place with a rigid plastic ring.
