EasyRoll Expanding Adaptor - Square Tube, 22 mm, M12 Bolt

The EasyRoll expanding adaptor is a 22mm adaptor for square tubing, with an M12 thread. The tube internal range for the 22mm size is 21.5 to 24.0mm.

Expanding adaptors are used with bolt hole castors to fit a castor to the end of round or square tubing. You screw the adaptor onto the threaded bolt that protrudes from the top of the castor, insert it into the tube and turn the bolt. The adaptor is compressed towards the head of the castor and expands inside the tube to hold the castor in place.
