Collection: 4" by 4-1/2" Top Plate Casters

Casters with a 4" by 4-1/2" top plate, a versatile mounting size found across medium and medium-heavy duty applications. This plate pairs a stable footprint with a bolt pattern common to industrial carts, platform trucks, and equipment bases. All casters in this collection share the 4" by 4-1/2" overall plate dimension for straightforward replacement matching. Filter by wheel type, load capacity, swivel or rigid configuration, and brake options.
