Therafin - Replacement Sliders are two thin slides, made of fiberglass. Each slider fits into the adjustable height channel bracket. These replacement slides offer extra weight and pressure support when using Therafin half trays. Therafin suggests using two slides at a time for a tighter fit and maximum support/pressure. For use with Therafin adjustable height channel bracket and Therafin half trays. Pair.
See video for samples on how to use the slider pieces. Note: Slider helps to prevent rips and tears on standard wheelchair arm rests when using half trays.
