A side plate with cable take-up reels, Model SPL-4H, can
be added to store excess cable length being fed to
installed equipment. The SPL-4H mounts to either side of
the WR-10U23 and includes two adjustable, split reels.
3. DESCRIPTION
The WR-10U23 (Figure 3) features welded steel, carrier-
class construction. The front of the frame provides two
vertical railswith standard threaded hole spacing for up to
ten rack units. Eight pairs of threaded grounding holes
and pre-installed screws are provided on the rear
crossbar for attachment of ground lugs. One pair of holes
supports grounding of the WR-10U23 itself and the other
seven pairs of holes support ground connections from
installed equipment. The unpainted grounding area
provides metal-to-metal contact with ground lug surfaces.
Cable Guides
Optional cable guides with removable covers (Figure 4)
can be attached to either side of the WR-10U23 frame.
Upto ten cable guides can be installed per side.
Side Plate with Take-up Reels
Anoptional side plate, Model SPL-4H (Figure 5), provides
two adjustablecable take-up reels. The reels are sized to
maintain proper bend radius infiber applications. The

Align the wide tabs at the front edge of the SPL-4H
with the threaded holes on the side of the WR-10U23
frame. Use the two (2) included #10-32 x3/8” screws
to securely fasten the side plate to the frame.
Carefullywrap cables around the take-up reels to
reduce slack as needed. Example routing is shown in
Figure 11. Alternate mounting holesare included on
