Friction Grip Ring Casters

Grip ring stem casters are available in two sizes and are intended to be inserted into tubing or a socket that is firmly affixed to the equipment. The grip ring, known as a compression ring, is located on the stem and compresses when pushed into the tubing or socket. This compression allows the ring to expand against the walls of the tubing, generating the necessary force to prevent the casters from dislodging if the equipment is lifted off the ground or floor.
