Rigid Plate Caster for Industrial Use
This Zoro Select rigid plate caster provides fixed-direction mobility for carts, dollies and material-handling equipment. It mounts with a standard plate and rolls on a single polyurethane wheel. The unit is sold new and carries California Proposition 65 warnings for listed chemicals.
Suited for Straight-Line Transport, Not Steering
The rigid design suits applications where the caster follows a fixed path and steering is handled by swivel units elsewhere. It has no brake and no swivel lock, so it cannot stop or pivot on its own. Buyers who need a self-locking wheel or a caster that turns should look at a swivel model with a brake.
250 lb Capacity with Non-Marking Polyurethane
The wheel supports a 250 lb load rating and uses a polyurethane tread on a polyolefin core that will not mark floors. At 3 inches in diameter and 1 1/4 inches wide, the tread handles smooth concrete and warehouse surfaces comfortably. It is not intended for heavy shock loads, rough terrain or continuous high-speed towing.

Questions about this item
What mounting plate does the 400K78 rigid caster need to attach to?
The caster uses a plate mount that bolts to a flat surface with four holes matching the plate pattern.
Can the 250 lb load rating caster be paired with older swivel casters on the same cart?
Yes, it will track straight while the swivel casters handle turning, provided all casters share the same overall height.
How do I confirm the polyurethane wheel is rolling correctly after installation?
Push the loaded cart; the wheel should roll smoothly, leave no marks on the floor, and show no wobble or binding.
