Stocked at our Mansfield, TX facility.
Compare set-of-4 configurations by wheel size, material, and capacity. All sets ship same day.
| Wheel Size | Material | Capacity (Set) | Configurations | Best For |
|---|---|---|---|---|
| 3" x 1-1/4" | Semi-Steel | 1,400 lb | All-swivel, 2-S/2-R, all-locking | Heavy appliance dollies, machinery moves |
| 4" x 1-1/4" | Semi-Steel | 1,400 lb | All-swivel, 2-S/2-R, all-locking | Heaviest furniture and shop dollies |
| 5" x 1-1/4" | Semi-Steel | 1,400 lb | All-swivel, 2-S/2-R, all-locking | Roll-over thresholds, uneven floors |
| 3" x 1-1/4" | Solid Polyurethane | 1,000–1,200 lb | All-swivel | Non-marking, finished floors |
| 4" x 1-1/4" | TPR Rubber | 1,200 lb | All-swivel | Quiet, non-marking, finished floors |
| 3" x 1-1/4" | Hard Rubber | 1,100 lb | All-swivel | Quiet rolling, light shock absorption |
| 3" - 5" | TPR Light Duty | 225–315 lb (each) | Swivel, top-lock brake | Light furniture, light cargo carts |
Add cargo weight + dolly deck weight. Divide by 4 casters, then add 30% safety margin for shock loads from thresholds and floor seams. Semi-steel sets hit 1,400 lb total (350 lb each) and handle heaviest dolly applications. TPR and rubber sets target 900-1,260 lb total for light-to-medium dolly use.
Smooth warehouse concrete: 3″ works fine. Door thresholds, expansion joints, light debris: 4″ minimum. Uneven floors, gravel transitions, outdoor pads: 5″ required. Larger wheels roll over obstacles with less push-force. Trade-off — bigger wheels raise deck height.
Semi-steel: rolls on rough concrete, may mark finished floors. TPR rubber: quiet, non-marking, good for finished commercial floors. Solid polyurethane: non-marking, abrasion-resistant, longest service life. Hard rubber: balance of quiet and capacity. Match material to dolly's typical operating environment.
All-swivel (4S): tightest turning radius, easiest sideways maneuvering. 2-swivel/2-rigid (2S2R): tracks straight in aisles, easier to push long distances. All-locking total brake (4S-TLB): for parked dollies that must stay put. Match config to how the dolly is used — storage vs transport vs precision positioning.
A matched set of 4 casters sold together with hardware, designed to mount on a furniture, appliance, or shop dolly. Sets come in all-swivel (4 swivel), 2-swivel/2-rigid (for straight-line tracking), or all-locking-swivel (with brakes) configurations. All sets in this collection use the standard 2-3/8″ x 3-5/8″ top plate that fits most commercial dolly frames.
3″ wheels for smooth floors and light cargo (under 1,000 lb), 4″ for door thresholds and medium loads (1,000-1,400 lb), 5″ for uneven floors, outdoor surfaces, or heavy industrial dollies. Larger wheels reduce push-force on rough surfaces but raise the dolly deck height by approximately 1/2″-1″ per inch of wheel diameter.
Semi-steel sets-of-4 in this collection hit 1,400 lb total (350 lb per caster). Polyurethane sets reach 1,000-1,200 lb, TPR rubber sets 900-1,260 lb, hard rubber 1,100 lb. Always size with 30% headroom over your actual load to account for shock peaks when crossing thresholds.
All-swivel for maneuvering in tight spaces (warehouse aisles, dock corners, furniture rooms). 2-swivel/2-rigid for long straight pushes (loading docks, hallways) — the rigid rear casters track straight while the swivel front steers. All-locking for parked dollies that must not roll under load.
TPR rubber, solid polyurethane, and hard rubber wheels are non-marking and safe for finished commercial floors. Semi-steel wheels may leave slight gray streaks on light-colored finished floors but are fine on concrete, asphalt, and unfinished surfaces. For showrooms and retail floors, specify TPR or polyurethane.
All sets in this collection use the industry-standard 2-3/8″ x 3-5/8″ top plate with 1-3/4″ x 3″ bolt-hole pattern. This is the most common dolly mounting pattern in North America. If your dolly uses a different plate size, contact engineering at info@casterhq.com or 844-439-4335 with measurements for cross-reference.
Yes — every set ships with 16 mounting bolts (4 per caster), washers, and lock nuts sized for 1/4″ or 5/16″ bolt holes on the standard dolly plate. Hardware is grade 5 zinc-plated steel. No additional fasteners required for standard installation.
No — all 4 casters on a dolly must be identical size and configuration. Mixing sizes creates uneven deck height and tilts the dolly toward the smaller wheels, concentrating load on those 2 casters and causing premature failure. If replacing, replace all 4 with the same set.
