Steers loaded carts and equipment on a 6-inch [152mm] solid rubber wheel that never goes flat. With no brake on the fork, the wheel rolls and the swivel head turns freely, so the caster tracks easily through tight turns and long pushes
Fits utility carts, tool and welding carts, garden and yard equipment, generator frames, and shop dollies that roll over gravel, asphalt, expansion joints, and cracked concrete where small hard wheels stall or chatter
A double-ball-bearing raceway in the swivel head provides smooth, low-effort steering under load. Flange-sealed ball bearings in the wheel hub keep dirt out and cut rolling resistance for long service on outdoor and shop floors.
Steel frame and top plate with bright zinc plating resist corrosion in damp shops and outdoor storage. Black semi-pneumatic solid rubber tread absorbs shock like an air tire, with no punctures, pressure checks, or refills
Rated 350 lb [160kg] per caster. Bolts on with a 4 x 4-1/2-inch [102 x 114mm] top plate at 7-1/2-inch [191mm] overall height, the same as the braked 511-66745854, so both can share one cart for a level, mixed setup
