4" JUMBO BLACK RUBBER FIXED

Engineered as part of the heavy-frame JUM series, this 4″ fixed caster provides exceptional straight-line stability and load support for industrial carts, mobile shelving, and equipment racks. Its rigid mounting bracket keeps equipment tracking accurately without lateral sway during long-haul transport.

The wide wheel profile distributes weight evenly to reduce floor point-loading while offering low rolling resistance under continuous load. Its heavy-duty construction stands up to daily physical wear in demanding commercial and warehouse settings.
