Light Duty Plate Casters are recommended for light assembly dollies, hand trucks, wire racks, and shopping carts. Light Duty Plate Casters are also used for rolling display racks, chests, and cabinets. Stem Mount casters are typically used when space is limited and a top plate won't fit on the application. As such, the majority of stem casters are considered light to medium duty.

Heavy Duty Casters are often used in manufacturing plants and warehouses to help move very large or heavy objects. Plate Mount Casters allow for a wider area of distribution of weight load and force compared to their stem mount counterparts, generally allowing plate mount casters to carry heavier weight loads.
