All measurements indicate the wheel diameter by the tread width.

The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

5" x 1-1/4" Polyolefin Casters

Plate sizes: 2-1/2 x 3-3/4Diameter: 4, 5 inTread: 1-1/4 inCapacity: up to 280 lb
Match a 2-1/2 x 3-3/4 top plate when bolting casters under light institutional and furniture-grade frames. Expect wheel diameters 4, 5 in, polyolefin treads, and capacities 230 to 280 lb. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
