These standards can be surface mounted or flush mounted inside a routed groove. Four shelf supports per shelf and four standards are required (sold separately).

Shelve your worries about dropping heavy and valuable rack components, from servers to router shelves. These supports create temporary ledges to let equipment—and your arms—rest as you set up your electronics rack. Each pack includes four supports, one to prop up each corner of the equipment. Simply snap them into the rack’s rail just below the level where you want to mount equipment. When you’re done installing, pop them right out.
