Wire Shelving Stem Casters

Wire-Shelving is an inexpensive way to increase the storage in your home, garage, workspace, or elsewhere. Shelves can be repositioned at precise 1″ (25mm) increments along the length of the numbered posts. Open-wire design minimizes dust accumulation, allows a free circulation of air, and greater visibility of stored items.

Wire-shelving such as TRINITY, PLACETECH, HDX, STYLE SELECTIONS, AMAZON BASICS, BEST OFFICE, TOUGH STUFF, SAFERACKS, MEMBER’s MARK, SEVILLE CLASSICS, and other brands are made with 1″O.D round tubing with a 3/8″ threaded stem insert for your caster. Our 3/8″ threaded stem caster can support much more weight than the casters that came with the shelving.

For customers that have removed this threaded insert, the Inside Diameter of the tubing is often 7/8″ and you can use a 7/8″ diameter Grip Ring stem caster, which we sell here:

Most wire shelving looks like this :

For a caster to be installed into round tubing, the manufacturers of wire-shelving usually weld a 3/8” diameter threaded nut into the tubing. From there you can screw in your 3/8” diameter threaded stem caster.

Caster City offers a wide range of suitable casters for your wire shelving. Most customers prefer polyolefin casters since they are hard, cannot develop a flat spot, and are inexpensive. Our most popular choice for replacement casters for your wire shelving is the following:

Polyolefin Caster Wheels are injection molded from a blend of thermoplastic polymers forming a one-piece solid sanitary design. These Polyolefin wheels are especially suited for wet and corrosive applications. They are very resistant to most commonly encountered liquids. This polyolefin industrial caster wheel cannot develop flat spots like other hard-composition wheels. This makes it especially attractive for wire-shelving applications that are infrequently moved. In a cold dry environment, such as a refrigerated storeroom, Polyolefin wheels may become brittle. They should not be used in a freezer or a heat application above 180°F intermittent usage, such as a rack washer.
