The Toner RS series of rack shelves are industry standard 19” rack shelves for mounting items in relay racks or cabinet type racks. The shelves are of a slotted shelf design for both ventilation and mounting of equipment. These equipment shelves (except the RS-1906S) feature a 3/16” lip at the front and back for increased strength and also to prevent equipment from falling off. All the shelves are black powder coated. A optional SRB-1 bracket is available to hold DSS type satellite receivers upright. The bracket engages in the slots in the rack shelf.
