Exterior Features
The features located outside the large main cabinet are de
scribed hereunder. See Paragraph 2.2 for the interior features.
2.1.1
Construction and Materials
The Boxer cabinet is designed to be weather‐tight for above‐
ground applications. As such, the powder‐coat painted alumi
num cabinet withstands many harsh weather conditions such as
rain, snow, and sleet.
2.1.2
Cabinet
The cabinet utilizes an “in‐the‐door” heat exchanger design.
Cabinet cooling is accomplished through the front‐door‐
mounted heat exchanger, fans, and vents. Security is provided
via cup‐washer screws. Mounting flanges (Paragraph 2.1.2.2) are
attached at the top and bottom of the back wall for permanent
mounting. The bottom floor of the cabinet contains numerous,
differently‐sized, intact knock‐outs (Paragraph 2.1.2.4) to ac
commodate a variety of cable, fitting, or conduit sizes and types.
2.1.2.1
Large Cabinet Door
A full‐size locking door provides ample technician and equip
ment access to the interior of the cabinet and also helps protect
the cabinet from tampering and vandalism. A full‐length hinge
supports the door in the open position. When the cabinet is
mounted and the door is open, the minimum clearance or dis
tance from the back of the mounting brackets to the outer edge
of the door's lock flange is 43.4” (as shown in Figure 23). At the
inside bottom of the door, near the hinge, a wind‐latch, shown
in Figure 2 and Figure 3, protects the door (and technician)
from possible wind damage. The wind latch restricts the door's
swing‐out angle to a safe but functional opening (105 degrees).
When the door is closed, an automotive‐grade sealing gasket
installed around the interior perimeter of the cabinet door
provides a weather‐tight seal to protect all equipment installed
in the cabinet. Both hex cup‐washer screws (door locks, see
Figure 2) can be loosened or tightened with a standard telco
can wrench or 216 tool. Additional door security is offered via
holes in the door flanges which accept a field‐provided lock or
padlock. The door sensors are described in Paragraph 2.2.1.
2.1.2.2
Mounting Brackets
Full‐width mounting brackets are provided at the back wall of
the Boxer cabinet, one at the top and one at the bottom. Each
bracket has nine mounting holes (top bracket) or slots (bottom
bracket). Use mounting fasteners with a diameter of up to
3
/
8
”.
The horizontal distance between holes is shown in Figure 10.
The vertical distance between the top and bottom mounting
bracket hole centers is 25.2”.
2.1.2.3
Heat Exchanger Compartment
The cabinet's cooling system is based in the door, in a heat ex
changer compartment (see Figure 5). The compartment has
vent holes, a heat exchanger, and fans. To access the heat ex
changer compartment, loosen the hex nut that secures it which
is located at the bottom, center, interior surface of the door
(shown in Figure 3), then lift up the compartment cover to
clear the cover‐alignment posts at the top of the compartment.
