ABSTRACT:
A protector for a pendant control is a protective cage formed by a pair of spaced ring-shaped bumpers joined by a plurality of connecting rods disposed around the bumpers. The cage is supported on the pendant control housing by a pair of spaced adjustable clamps, each clamp being attached to a bumper by at least two, and preferably three, shock absorbing members, such as coil springs, which are preferably disposed equidistant from one another about the bumpers and clamps to maintain the cage substantially concentric with the pendant control housing.
