The CableTronix CT-CASTERSET42WL caster set of four separate wheels are intended to be an add-on to any products mounted into a compatible equipment rack. The presence of the casters allows the potentially very heavily loaded rack to be easily moved through a facility, and allows for easy navigation if the rack requires mobile applications through the facility. The CableTronix caster set of four separate mountable wheels features two wheels capable of braking, and two standard non-braking wheels. A rack base with all four wheels installed has a weight limitation of 400lbs, and each wheel facilitates up to 4x screws with a mounting area of 2.375" x 3.375", this product includes all needed mounting hardware.
