A Balanced Caster Configuration for Controlled Movement

This heavy-duty set combines 2 swivel casters with total locks and 2 rigid casters. The swivel casters provide steering control, while the rigid casters help the equipment track in a consistent direction. It is a practical configuration for carts, cabinets, workbenches, racks, and equipment that must roll when needed and stay positioned when parked.

Total Lock on the Two Swivel Casters

Each swivel caster includes a foot-operated total-lock brake. When engaged, the brake locks both the wheel and the swivel head to help prevent rolling and unwanted pivoting. The two rigid casters are non-swiveling and do not include brakes.

PU Tread With a Cast Iron Core

The red polyurethane tread helps provide smooth, quieter rolling and reduced floor marking on clean hard surfaces. A cast iron wheel core adds structural support, while double sealed ball bearings help the wheel roll smoothly under load.

Zinc-Plated Steel Plate-Mount Brackets

Each caster uses a zinc-plated steel mounting bracket and a four-slot top plate. The included hardware makes it easier to mount the full set to compatible equipment. Before installation, compare the top-plate size, slot dimensions, hole spacing, equipment material, and available clearance.

Select the Right Size

The 3 in caster set supports up to 1,410 lb total and uses a 3.71 x 2.53 in top plate. The 4 in caster set supports up to 1,984 lb total and uses a 3.70 x 2.52 in top plate.

Load capacity applies to the complete set of four casters with evenly distributed weight. Always select a capacity that accounts for uneven loading, floor conditions, equipment movement, and a suitable safety margin.

Complete Mounting Kit Included

Each set includes 2 total-lock swivel casters, 2 rigid casters, 16 bolts, 16 nuts, 16 flat washers, 16 split lock washers, and 2 wrenches.

FAQ

What is included in this set?

Each set includes 4 plate casters: 2 swivel casters with total-lock brakes and 2 rigid casters. The package also includes 16 bolts, 16 nuts, 16 flat washers, 16 split lock washers, and 2 wrenches.

Do all four casters swivel and lock?

No. Two casters swivel 360 degrees and have total-lock brakes. The other two are rigid casters that roll in a fixed direction and do not have brakes.

What does the total-lock brake lock?

On each locking swivel caster, the foot-operated total lock secures both the wheel rotation and the swivel movement. This helps keep compatible equipment from rolling or pivoting while parked.

What is the load capacity?

The 3 in set supports up to 1,410 lb total. The 4 in set supports up to 1,984 lb total. These ratings apply to the complete 4-caster set with the load distributed evenly. Actual working capacity also depends on the equipment, mounting surface, floor condition, and how the load is positioned.

Which size should I choose?

Choose based on the required load capacity, available clearance, and mounting dimensions. The 3 in version has a 1.1 in tread width and supports up to 1,410 lb per set. The 4 in version has a 1.2 in tread width and supports up to 1,984 lb per set. Confirm the top-plate and hole spacing before ordering.

Are these casters suitable for hardwood or epoxy floors?

The polyurethane tread is designed for quiet, smooth rolling on clean hard surfaces such as sealed concrete, tile, hardwood, and epoxy flooring. Keep the wheels and floor free of grit or metal debris, as trapped debris can still damage flooring.

Are these plate-mount or stem-mount casters?

These are plate-mount casters. They attach through the four mounting slots in the top plate and are not compatible with threaded-stem, grip-ring-stem, expanding-stem, or bolt-hole caster mounts.

Can I use these outdoors or on rough terrain?

These casters are best suited to smooth, firm surfaces. They are not designed as pneumatic, all-terrain, off-road, or gate casters.
