The RRN-44 mounting rails are made to fit narrow (22-inch wide) 44U LGNR rack series, which feature side channels to adjust rail positioning deeper into the rack if needed. RRN rails are 11-gauge U.S. steel with a black powder epoxy finish and printed RU scale to facilitate set-up. The 1U position should be placed at the bottom of the rack for consistent loading of equipment. RRN rails accept threaded 10-32 screws. Sold in pairs. Note: See video below for information on Lowell's 4 types of rack rails.
