Rack-Ware products are designed to be compatible with most boltless steel shelving that have either wedge style, keyhole style, or rectangular style hole openings that are 1.5" or 3" on center, but no accessory should be assumed to fit every rack.If you are uncertain, contact us with photographs and measurements of your rack, and we will make a reasonable effort to help determine compatibility and add to our growing list of known compatible brands.
