Slotted standards are a quick and easy way to add adjustable shelving, hangrail and faceouts to any wall. Choose 1/2" slots/1" on center or 1" slots/2" on center. Our wall standards are engineered for commercial use, not like thin standards sold at home centers. Store Supply Warehouse has all Slotted Standards Hardware & Accessories available for super fast shipping and the lowest prices guaranteed for all of your fixture needs.
