This set of four 8-inch scaffolding casters is built to move and secure heavy equipment on the job site. Each wheel is molded from non-marking polyurethane over a cast-iron core, rolling quietly across floors without leaving marks, while the non-welded carbon steel frame keeps the assembly rigid under load. Every caster carries up to 1100 pounds on its own, giving the set of four a combined 4400-pound capacity for scaffolding, workbenches, and shelving. Each wheel swivels a full 360 degrees for easy maneuvering in tight spaces, and an integrated brake locks both the wheel and the swivel at once, holding equipment firmly in place so it will not roll away while you work. At roughly 8 inches in diameter and 53 pounds for the complete set, these red casters suit scaffolding towers, storage shelves, and workbenches that need to move occasionally but stay put the rest of the time.
