ASSEMBLY INSTRUCTIONS
STEP A (Refer to Figure A on left)
Strip cable to suit equipment as shown above,
exposing metal armor sheath (I) and insulated
cores (II).
I = 3/4” (19mm) for ½” size glands
I = 13/16” (21mm) for ¾” size glands
I = 1” (25mm) for 1” size glands
I = 1-1/4” (32mm) for1-¼” size glands
II to suit equipment
STEP B (Refer to Figure B on left)
Push the cable through the back nut (1), middle
nut (2), and grounding spring (3). Locate the armor
stop (4) at the end of the armor as shown below. If
the conductors are too large to t through the armor
stop (4) it can be removed from the assembly. The
elbow component (5) has a built in armor stop for
larger cables. Feed the wires through the elbow
and tighten the middle nut (2) and backnut (1) to
the torque shown in Table A (Approximately hand
tight + 1 turn). This will compress the grounding
spring (3) to grip the armor for grounding.

STEP C (Refer to Figure C on left)
If the gland is to be installed in a threaded opening
rst thread the entry component (8) into the
enclosure to prevent twisting of the cable. When
installing the entry component (8) into a NPT entry
the component should be installed hand tight and
then one additional turn with a wrench.
If the entry component (8) is installed into a thru hole
with a locknut, rst thread the entry component (8)
into the locknut. The entry component (8) should
be tightening to the torque shown in Table A
(Approximately hand tight +1 turn).
Thread the locking collar (6) onto the entry
component (8) to the torque show in Table A. This
is to prevent twisting of the cable during assembly.
