Lowell RRD Series 10-32 Rack Rails With Hardware for 23" Wide Rack | 40U

The Lowell RRD Series rack rails are designed for AV integrators and installers who need reliable replacement or supplementary mounting rails for 23-inch wide rack enclosures. Compatible with Lowell LER, LFR, LSER, LGR, LSGR, LPR, LWBR, and LWR rack series, these rails fit into side channels that allow rail positioning to be adjusted deeper into the rack as the installation requires. Each pair positions equipment consistently from the bottom up, following the 1U-at-bottom convention that professional rack builds demand.

Constructed from 11-gauge U.S. steel with a black powder epoxy finish, the RRD Series rails are built to the material standards expected in permanent installed-sound and AV system enclosures. Threaded 10-32 round holes accept standard rack screws, and a printed RU scale printed directly on each rail eliminates guesswork when staging gear before final installation. Mounting hardware ships with every pair, so no separate hardware order is required.

Available in a wide range of rack-unit sizes to match the depth of the enclosure being outfitted, the RRD Series gives integrators the flexibility to refresh or expand existing Lowell rack infrastructure without replacing entire enclosures. TAA and BAA compliance makes these rails a practical choice for government, education, and public-sector AV projects where domestic sourcing is a procurement requirement.
