The large stem on these casters fits into scaffold frames and round tubing. All casters have a total lock that brakes the wheel and locks the swivel in one operation.

All wheels have an iron core for strength. Rubber treads are shock absorbing and provide good traction on rough surfaces. Polyurethane treads combine the abrasion resistance of plastic with the shock-absorbing qualities of rubber. They can be used on smooth and rough floors and in areas with debris.

Roller wheel bearings provide smooth rolling and are shielded to resist dust and debris. Casters have double-ball swivel bearings for the smoothest swiveling.
