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.
Capacity shown is per caster (per wheel for wheels).
























Find the right toolbox caster path
Measure plate or stem first, then shop a set of 4. This hub is for rolling toolboxes and tool chests — not shopping-cart stems, fab weld-on pads, or powder-oven heat wheels.
Buying guide: Toolbox Casters & Tool Chest Wheels · Fit note: no Exact OEM Snap-on / Husky / Craftsman claims — measure and confirm on the PDP.
Plate vs stem, capacity, and 2+2 brake layout before you order.
Stay on this hub. Filter by wheel diameter and compound; confirm set capacity on each PDP.
Threaded, expanding, or grip stem. Measure type and diameter first.
Use titles on this hub for TPR, polyolefin, polyurethane, and phenolic. Confirm set capacity on the PDP.
Shop matching size here; replacing all four is often cleaner for brake layout.

Weigh or estimate the loaded box and divide by three to get the load per caster, since one corner often lifts on an uneven floor [S3]. Some sets with blue solid polyurethane wheels have stainless steel rigs [S1].
Heavy phenolic sets: phenolic casters on a 4 x 4-1/2 in plate. Locking options: total lock casters.
It depends on the box. Smaller boxes and carts often use 3 to 5 x 1-1/4 in casters on a 2-3/8 x 3-5/8 in plate. Large roll cabinets often use 4 to 8 x 2 in casters on a 4 x 4-1/2 in plate. Measure your plate and bolt holes before ordering.
From 800 lb for small TPR sets to 5,000 lb for 6 and 8 in polyurethane and phenolic sets.
A caster whose brake locks the wheel and the swivel together, so the box cannot roll or turn.
Polyurethane for heavy boxes and quiet rolling, phenolic for oil and heat, semi-steel for welding areas.
