A cart or equipment base that doesn't roll makes any mobile setup a two-person job when it should be one. This black swivel caster has a 3-inch wheel that rolls over thresholds, cords, and slightly uneven floors without hanging up, and the swivel base lets the load pivot naturally as you move rather than fighting the casters. The 100-pound rating covers most tool boxes, equipment dollies, and轻 work carts without being overkill. Standard in the fabrication and assembly shops of manufacturers and property maintenance crews across northeast Nebraska and northwest Iowa.
