Selecting the proper caster mounting method is critical for safety, structural integrity, and long-term durability. Improper mounting can lead to frame failure, load imbalance, and premature caster wear.
Plate mount casters use a rectangular top plate secured with four bolts. This is the strongest and most common mounting style for industrial carts and heavy equipment.
