Caster Socket for 7/16" Grip Ring and 0.652" ID Square Tube - RT650SQ

About This Caster Socket - RT650SQ

Use this socket to turn a slim 0.652-inch square tube leg into a tool-free mount for a grip-ring stem caster.

A caster socket is a sleeve that seats in the open end of a hollow tube leg and gives it a round bore sized to hold a caster stem, so a light cart, rack, or display fixture built from thin square tube can take a standard caster without welding a plate or tapping the tube. This one fits a 0.652-inch inside-diameter square tube and accepts a 7/16-inch grip-ring stem, the sprung-ring stem that pushes in and holds without a nut, so casters drop in and pull out by hand for service. Match the socket to your exact tube ID, as the 0.620 and 0.652 square sizes are close.

Ideal applications

• 0.652-inch ID square tube legs on light carts and fixtures
• Tool-free 7/16 grip-ring mount in a 0.652-inch square tube
• Slim tube frames that need a caster without welding a plate

For a slightly smaller square tube, the 0.620-inch RT620SQ takes the same 7/16 grip-ring stem.

Pairs with: four 7/16-inch grip-ring stem casters and a square-tube frame built to 0.652-inch ID.
