The Leg Holder Disposable Pad is compatible with all Allen® leg holder systems. These pads utilize two special foam materials which are laminated together. The outer pad is a dense, slightly compressible material which allows for high clamping pressure to stabilize the leg. The inner pad is a soft, fully compressible material for gentle, non-abrasive contact with the skin. The leg pad secures with simple Velcro® fasteners.
