These are tough, dependable casters in a range of sizes. Resistant to grease, oil, adhesives, kerosene-based solvents and UV, the solid polyurethane tires are extremely durable and non-marring. Each caster rotates on a ball-bearing race and has a foot-operated brake mechanism.
On the three largest sizes, the brake simultaneously locks the wheel and swivel base; on the 2" size, it locks the wheel only.
Nominal sizes listed are wheel diameter by overall height, with weight capacity in brackets.
