Donut Bumpers for Swivel Casters

These 3-inch diameter rubber donut bumpers provide cushioned contact between mobile wire shelving units and walls, fixtures, or adjacent equipment. The non-marking rubber construction absorbs impact and prevents scuffs during repositioning or incidental contact, making them a practical protective addition to any caster-equipped shelving setup.

Well suited for warehouse stockrooms, retail backrooms, fulfillment centers, and light industrial storage areas, these bumpers help reduce surface damage and noise when shelving units are moved or come to rest against walls and fixtures. The donut profile seats securely around the caster stem without tools or additional hardware.

Compatible with swivel casters designed for wire shelving systems, including standard four-caster configurations. Sold in cases of 4 — enough to outfit one shelving unit — and lightweight at 0.72 lbs per case for easy handling and restocking alongside other wire shelving accessories.
