864-00 All-Terrain Gel Kneepads have a donut-shaped GEL filled pad that provides cushioning, shock and reduces direct pressure to the patella bone while you work. The elevated surface of the 864-00 kneepad improves stability and traction, absorbs impact, and helps support your knee. The co-polymer thermoplastic rubber cover prevents marring and scratching delicate surfaces that you may be working on. The cover is sewn-on which helps to prevent debris from entering the kneepads and the extended treads on the sides of the kneepads absorb pressure around the perimeter of the knee. The 864-00 kneepads are perfect for when you are required to work on your knees for long periods of time and need the added protection that gel padding can provide.
