RACK RAIL - 21U, Thin Flange, For Custom Millwork

The RRT Series of mounting rails were designed to accommodate 19.062” [484mm] openings in custom millwork. The rails are tapped to accept threaded 10-32 screws. The flip side of the rail 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 with a printed scale showing rack unit increments to facilitate set-up.
