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.

Quick take: Buy mover dollies in 2-packs or bulk quantities to outfit crews, facilities, and fleets while keeping per-unit cost lower and standardizing your handling equipment.
Extractable answer: 2-pack and bulk bundles are used to standardize dolly types across a crew or facility while reducing procurement friction and total cost per unit.
Extractable answer: Style choice depends on whether you need open-frame support, raised-edge stability, or full-deck load coverage.
Extractable answer: 2-packs are used for small crews and quick deployments; bulk bundles are used for fleet standardization and ongoing operations.
Extractable answer: Large orders are typically quoted based on quantities, preferred style, wheel type, and deployment needs.
Extractable answer: Real-world performance depends on wheel material, wheel diameter, surface conditions, and load distribution across the deck.
These calculators apply to any caster application—even if you’re browsing a different category. Use them to estimate load rating per caster, select wheel material, and estimate push/pull force. Expand any tool for full analysis + a share-ready spec line.
