Made from rubber with a U-shaped steel insert, this post protector provides long-lasting protection against rack damage. The rubber compound features greater elasticity than other post guard materials, giving it a unique ability to absorb energy and deflect impacts. Because this patented design has been tested for multiple strikes, it's a good choice for high-traffic settings. It snaps snugly on a 3"W x 3"D post to protect against front, angled and side impacts, with no tools needed for installation. An adapter kit is available to fit 1-5/8" and 3" structural posts - see the Accessories tab below.
