Determine the socket you need by measuring the Inside Diameter of the tubing and matching that to the outside diameter of the socket. The sockets are usually quite long-lived. It"s only function is to keep the casters (or glides) from falling out when the application is lifted. Most of these are for hollow tubing, wood or weld-on applications. Various styles are for grip ring stems, grip neck stems and threaded stems.
