The Edsal heavy duty steel shelf units from Home Depot and the like (http://www.homedepot.com/p/Edsal-48-in-W-x-72-in-H-x-24-in-D-Steel-Commercial-Shelving-Unit-UR-245/100095394) make a great work bench when assembled as two side-by-side shelves. Unfortunately, they only come with one set of feet. This item is a replacement for the stock feet to keep your floor from getting scratched or to replace broken feet.This foot fits a 2mm x 34mm right angle, filleted leg. I gave it .5mm extra tolerance.  It's a tight fit but stays on.
