Product Overview Crafted from comfortable silicone material, the Heel Strap attaches to the Raiser Pro's turning knobs on either side, offering stability and support to the user's heels while standing on the base plate of the Molift Raiser Pro Sit-to-Stand Transfer Platform. With two holes on each side, the Heel Strap can be easily adjusted to three different lengths, providing a customisable fit for various users. It's important to note that the wheels must be locked before the heel strap is mounted onto the turning knobs.
