The 300 Series wall cabinets
are welded with center-section depths of 12” and 15”, respectively. Basic model
includes three, 16-gauge CRS sections which include a 2” deep, solid-steel front
door, a 12” or 15” deep center section with adjustable mounting rails, and a
4-1⁄2” deep rear door. Panel space openings range from 7 RU to 35 RU. Enclosures
are equipped with provisions for custom cabinet mounting, wire management,
equipment mounting, and structural support. Cabinet is
finished in #962 black epoxy.
include adjustable front rack rails tapped 10–32, and manufactured to standard
E.I.A. 1⁄2" spacing. Models with RU openings of 16RU, 24RU and 35RU are equipped
with center section mounting rail supports.
raceways provide cable pathways in the cabinet. Corner brace supports, which
straddle the back and side panel of the rear section (hinge side), also feature
round (1-1⁄4" diameter) wire access holes for harnessing excess wire. The back
face of the rear section is equipped with 1⁄4" deep boss detents which give
Contractors field flexibility to install a custom plywood, aluminum, or steel
sub-plate for mounting accessories inside the cabinet. Boss detents are on 12"
centers and vary depending upon model height (10RU, 12RU, and 16RU models have
four detents, 24RU models have six detents and 35RU models have eight
have 20 conduit knockouts on the rear section, with the exception of the 307-12
which has 16. Conduit arrays are located at the top and bottom of the back panel
(except 307-12 which has a centered array), as well as on the top and bottom
back flanges. Panel arrays consist of four knockouts: two 1" (25mm) standard and
two 1⁄2" (13mm) / 3⁄4" (19mm) concentric. Top and bottom flange arrays are
comprised of six knockouts: three 1" (25mm) standard and three 1⁄2" (13mm) /
3⁄4" (19mm) concentric.
vents, located on both sides (top and bottom) of the center section, provide
ventilation for rack-mounted electronics.
offer exceptional structural support. The units’ one- piece front and rear
sections are strengthened with frame flanges on bottom, top, and sides. Center
sections are plug-welded, joining bottom and top panels to side panels. Rear
sections have corner brace supports which bridge the back and side panel (hinge
side) giving the back (mounted) panel extra reinforcement for tension
have electric-welded seams and miters which increases the cabinets’ overall
bonding. The center section offers maximum reinforcement provisions, such as a
uniquely designed center section guide plate that reduces potential sagging by
distributing cabinet and equipment weight to rear section. The 11-gauge, 17⁄8"
wide guide plate, which mounts to the rear section’s bottom flange, provides a
3⁄4" lip for added support to the center section when the cabinet is open or
closed. The plate also ensures that an equipment-weighted center section will
close properly, by “guiding” alignment pins into respective holes. An optional
caster for carrying the weight of the center sections is available (Atlas
