Rack Railswith Dual-hole pattern

escription:

D

The RRD-series of reversible mounting rails were designed to ac­commodate different types of hardware on a single rail. The dual-

ole pattern rails are tapped on one side (to accept threaded

h
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.

Features:

• Rails include fixed hole positions to secure the rail during
transportation or on the job site when forward/backward move­ment of rails (and loaded equipment) is not desired.

• 11-gauge steel

• Black powder epoxy finish

• Made in the USA with 100% certified US steel

• For use with Lowell rack models LER, LER-F, LGR, LSER,
LSER-F, LSGR, LPR, LPPR, and LWR.

• Sold in pairs

Note: If a full size rail is not needed for racks 24U or taller (e.g.
extra support is only needed for equipment at the top or bot­tom of the rack), order rack rail model no. RRD-21. This short
rail is unique in that its hole pattern is designed to align not
only with 21U racks but also with the top or bottom of taller
racks. This provides an economical way to support the rear of
rackmounted equipment when a full size rail is not needed.
