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.

2-3/4 x 3-3/4 inch top-plate casters for light institutional and furniture-grade frames. You will see wheel diameters 2-1/2, 3, 4 in and capacities 200 to 375 lb across the SKUs listed below. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set.
