Payson Casters, Inc Light- Medium Duty, Swivel, Total-Locking Bolt-In Stem Caster for Scaffolding; 800 lb. Load Rating, 8" Wheel Dia.

These bolt-in stem casters have a round stem that fits into structural framing made of round metal tubing. Each caster has a total-lock brake that can be engaged to prevent the caster's wheel and swivel mechanism from moving. Sometimes called scaffold casters, these casters are used on light-duty scaffolding, work platforms, workbenches, and tables that will be moved frequently but must be kept stable and immobilized when people are using them. They can help prevent injuries that may be caused if the casters roll or turn unexpectedly. These casters have zinc-plated steel frames and double ball swivel bearings that allow the caster to swivel smoothly. They are suitable for janitorial, maintenance, painting, electrical, and construction applications.

These bolt-in stem casters have a round or square stem that fits into structural framing made of metal tubing or angle iron. They can be attached to scaffolding, racks, and carts built from structural framing to allow the equipment to roll as its being moved or repositioned, which reduces the effort required to move the equipment. In general, the shape and size of the stem determines the type of frame the caster will fit into, and bolts or pins are installed into cross-drilled mounting holes in the framing and the caster's stem to secure the caster in place on the framing.
