4" x 1.25" Polyolefin Casters

Diameter: 3-1/2, 4, 5 inTread: 1-1/4 inCapacity: up to 300 lb
This collection gathers plate-mount casters used on light institutional and furniture-grade frames. Expect wheel diameters 3-1/2, 4, 5 in, polyolefin treads, and capacities 230 to 300 lb. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Replace worn corners in matched sets when possible so the cart tracks straight under load. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
