Lowell RRD-44
(2) 44 RU Rack Rails with Dual-Hole Pattern


The RRD-series of reversible mounting rails were designed to accommodate different types of hardware on a single rail. The dualhole pattern rails are tapped on one side (to accept threaded 10-32 screws) and square-punched on the other side (to accept 12-24, 6mm, or 10-32 hardware with cage nuts). The rails also feature a printed scale showing rack unit increments to facilitate set-up. The easy-to-read rack units and symbols for 1U and 2U loading patterns are printed on both the tapped and punched side of each rail. The 1U position should always be placed at the bottom of the rack to facilitate consistent loading of equipment. The flip side of the rail (tapped or punched) can be used to mount rack accessories or to manage wires and cables. Rails are made from sturdy 11-gauge steel and have a black powder epoxy finish.
