Other Size Steel Casters
Non-standard steel wheel casters — 4-inch, 5-inch, 8-inch, 10-inch diameters. For specialty containers and oversized heavy-duty dumpster applications.
What this page covers
Most steel-caster commercial applications use the 6-inch standard. The non-standard sizes serve specialty containers (smaller industrial bins, vault waste) and oversized heavy commercial dumpsters where extra ground clearance matters.
PRT stocks these sizes for specialty applications.
How to choose
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.

Frequently asked questions
When would I need a non-standard steel caster size?
Smaller industrial bins, vault waste, or larger 6-8 yard heavy commercial dumpsters where 6-inch ground clearance is insufficient.
Are non-standard steel casters significantly more expensive?
20-50% more than 6-inch equivalents due to lower production volumes.
Do non-standard sizes use standard mounting plates?
Yes — standard NEMA hole patterns across all PRT caster sizes.
How long do larger steel casters last?
Effectively unlimited under normal service. Bearing wear is the typical end-of-life condition.
