This unused set of four (4) 3" swivel poly casters (all with brakes) is made for wire shelving units I bought from Omega Products.

The casters are medium duty (800 lbs total capacity). Included are the threaded inserts that fit the wire shelving tubes — see photo.

See also the screenshot of the same casters I located on Omega Products’ website: precisiontools.com

Plus…

Happy to include two (2) unused 4” wheels I found, plus a set of four (4) unused 1-⅝”casters.

Also…

4 screw-in bases are included — see last photo.

All unused like new.

Cheers!
