4Pc 8 Inch Heavy Duty Rubber Caster Wheels With Brake Lock & Mute Ball Bearing
These big castors are very heavy duty, stronger than most! They are brand new from an opened box. The hard rubber tires are 1 1/2 inch wide where they touch the floor. The steel plates are 4 1/2 by 5 1/2 inches.
The mounting bolts/screws are pictured. All four wheels have good swivel bearings, and two have sturdy brakes!
