Grip Ring Stems

Grip ring stem casters come in various different sizes are are designed to fit up into a mounting hole or socket to securely attached the caster to the mounting unit. The grip ring is a brass ring on the stem that compresses as it pressed up into the mounting hole. It is squeezed and then expands against the tubing walls which creates the force that keeps the casters from falling out. Load capacities range from 80lbs to 150lbs.
