Non-standard phenolic casters — 4-inch, 5-inch, 8-inch wheel diameters for specialty containers and heavy-duty applications in high-heat environments.
Most commercial dumpster phenolic applications use 6-inch wheels, but smaller specialty containers (commercial-kitchen carts, small heat-tolerant bins) use 4-inch and 5-inch phenolic, and heavier commercial containers in high-heat industrial use 8-inch.
PRT stocks the non-standard sizes for these 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 containers (small recycling carts, vault waste, food-service equipment carts) use smaller phenolic casters. Larger 6-8 yard heavy commercial dumpsters in industrial high-heat use 8-inch.
Slightly. The premium covers the lower production volume; the per-unit cost is typically 10-25% higher than 6-inch equivalents.
Yes. Standard NEMA mounting hole patterns across all PRT caster sizes.
3-inch is the smallest standard. Smaller sizes are available on custom order.
