Non-standard polyurethane casters — 4-inch, 5-inch, 8-inch, and 10-inch wheel diameters. For specialty containers, recycling carts, and heavy outdoor commercial dumpsters.
The 6-inch standard covers most commercial dumpsters, but specialty containers and oversize applications need other sizes. Smaller polyurethane (4-inch and 5-inch) for recycling carts. Larger (8-inch and 10-inch) for 6-8 yard heavy commercial dumpsters where ground clearance and load capacity matter.
PRT stocks these sizes for specialty applications.
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.
Specialty container fitment or load requirements. Recycling carts use smaller casters; heavy 8-yard commercial dumpsters benefit from 8-inch or 10-inch casters for better ground clearance over cracked pavement.
10-30% more than equivalent 6-inch sizes — lower production volumes carry a small premium.
Yes — standard NEMA hole patterns across all sizes.
