These construction knee pads are designed to minimise the risk and provide protection for working in a kneeling position and immediate injuries from hard surfaces and small stones or similar objects on the surface. The heavy duty plastic caps on the exterior provides a stable platform for stationary work, kneeling on narrow surfaces and crawling as well as turning on your knees. The thick foam padding is incorporated for maximum comfort. These knee pads are intended to be placed on your knee and strapped on in a comfortable and stable position. Adjustable straps with slide buckle style fastening provide a comfortable and a secure fit.
