Caster Kit Dimensions
The Rubbermaid Caster Kit measures 19 in long by 21 in wide with an overall height of 5 in. It includes two rigid casters, two swivel casters and mounting hardware in a single four-piece package.
Rigid and Swivel Mix
The combination of rigid and swivel casters lets a platform move straight under load while still turning in tight spaces. Hardware is supplied so the kit can be bolted to compatible equipment without sourcing separate fasteners.
Load Rating Limit
Each kit is rated for a maximum capacity of 2,100 lb, so any application above that figure requires a different solution. Buyers needing a higher load rating or a different wheel material should look elsewhere.

Questions about this item
When will the 2100 lb capacity casters need replacement under daily warehouse use?
Replace casters when wheels develop flat spots, bearings become noisy, or mounting hardware loosens beyond safe adjustment — typically after several years of loaded service on smooth concrete.
What limit appears first when the 19×21 in kit carries 2100 lb continuously?
The 2100 lb rated capacity is the primary limit; exceeding it risks wheel deformation, bearing failure, or hardware stress before any other constraint becomes critical.
How much heat or noise do the rigid and swivel casters generate during all-day rolling?
Casters produce minimal heat and low rolling noise on smooth floors; swivel bearings may emit a faint click under heavy loads, but neither affects ambient conditions.
