6-inch polyurethane casters for commercial outdoor dumpsters — the standard size, long-wearing, weather resistant, and floor-friendly. The default upgrade from 6-inch mold-on-rubber for outdoor service.
The 6-inch wheel diameter is the commercial dumpster standard; polyurethane is the outdoor-service material standard. Together they make the most-stocked caster combination for commercial waste operations that include outdoor dumpsters.
PRT stocks 6-inch polyurethane in swivel and rigid configurations with load ratings appropriate for 2-yard through 6-yard commercial service.
Match by load rating, wheel diameter, mount type (bolt-on or weld-on), and caster type (swivel or rigid).
Send PRT a photo of your existing caster with the container model number and we'll confirm fitment.

Adequately. Polyurethane stays flexible in cold; the tread doesn't harden the way rubber can. For severe-winter routes, specialty cold-rated polyurethane is available.
