4 x 4 inch top-plate casters for light institutional and furniture-grade frames. Typical builds show wheel diameters 3-1/2, 4, 5 in, polyolefin treads, and capacities 250 to 350 lb. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
