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 available in several sizes, 1RU (1.750”) 2 RU (3.50”) and 3 RU (5.25”) and all 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.
