All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.
Replacement wire shelving casters for the most common wire shelf rack systems — Metro, InterMetro, Quantum, Eagle, and other 1-inch shelf-post systems. Polyurethane and TPR rubber wheels in 3" through 5" diameters, swivel and locking configurations. Fits the standard 1-inch shelving post via a press-fit threaded socket. Stocked at our Mansfield, TX facility.






Compare wire shelving caster configurations by wheel size, material, lock type, and capacity. All fit the standard 1-inch shelf post used on Metro, InterMetro, Quantum, Eagle, and most U.S. wire rack systems.
| Wheel Size | Material | Capacity | Lock | Best For |
|---|---|---|---|---|
| 3" Wheel | Polyurethane | 300 lb | Swivel | Light commercial shelving, retail back rooms |
| 3" Wheel | Polyurethane | 300 lb | Total Lock | Shelving that must hold position when loaded |
| 4" Wheel | Polyurethane | 300 lb | Swivel | Mid-duty wire racks, commercial kitchen |
| 5" Wheel | Polyurethane | 300 lb | Swivel | Heavy wire shelving, threshold crossing |
| 5" Wheel | TPR Rubber | 250 lb | Swivel or Brake | Hospital, lab, food service (quiet) |
The vast majority of U.S. wire shelving (Metro, InterMetro, Quantum, Eagle) uses a 1-inch outer diameter post with a tapered split end and a notched groove. These casters are designed for that 1-inch post. If your shelving has a different post diameter (smaller European systems often use 25mm or 19mm), measure first.
3-inch wheels for indoor smooth floors and tight aisle clearance. 4-inch and 5-inch for larger wire racks, uneven floors, threshold crossing, and warehouse environments. Larger wheels roll over obstacles better but raise overall shelf height.
If the shelving will be moved frequently and parked in various spots: free-swivel. If the shelving holds inventory and must stay put when loaded: total lock (wheel + swivel) or side-lock brake. Hospital, lab, and food service environments usually want lock.
Polyurethane handles higher load (300 lb), is non-marking, and is the default for retail and commercial. TPR rubber is quieter, gentler on tile and vinyl, but lower capacity (250 lb). Hospital and food service typically want TPR.

Step-by-step installation walkthrough showing how to remove existing wire shelf foot caps, insert the caster, and snap into the standard 1-inch post.
CasterHQ stocks the complete range of 1-inch post wire shelving casters — polyurethane and TPR rubber, 3" through 5" wheel diameters, swivel and total-locking variants — at our Mansfield, TX facility. Compatible with Metro, InterMetro, Quantum, Eagle, and other U.S. wire shelf systems. 99 percent ship same or next business day.
The wheel size depends on use: 3-inch for indoor smooth-floor light shelving. 4-inch or 5-inch for mid-duty or heavy wire racks. The post-fitment is the same on all our casters: 1-inch standard post.
Yes — these are designed for the standard 1-inch outer-diameter post used by Metro, InterMetro, Quantum, Eagle, and most U.S. wire shelving brands. If your shelf is European or older than 1990, measure first.
Remove the existing foot cap from each shelving post. The caster has a tapered insert sized to the 1-inch post. Push the caster firmly onto the post until the friction lock engages. Tap with a rubber mallet to seat fully. No tools beyond a mallet required.
Most polyurethane wire shelving casters are rated 300 lb per caster. A 4-caster shelving unit handles 1,200 lb total. TPR rubber variants are rated 250 lb (1,000 lb total). Add 25 percent headroom over expected load.
Many variants include a side-lock brake or total lock so the shelving holds position when loaded. Pick locking if the unit holds inventory; pick free-swivel if it moves constantly.
Polyurethane and TPR rubber wheels are both non-marking on tile, vinyl, and polished concrete. Both work well in retail, commercial kitchen, hospital, and food service.
Yes — if your shelving currently has different casters, remove the old ones (usually a press-out from the post) and press the new CasterHQ casters in. Same 1-inch fit covers virtually any replacement scenario.
