Use the

Lift the case. (The recommended way to lift the case is to use a sling attached through the opening in the
doubler enclosure.) Secure the case to the mounting bracket with the four T-bolts.

Splice the stub. (See
spliced to either air-filled core cable or gel-filled core cable.
•
Enclosure cases spliced to air-core cable should be maintained under pressure from the cable. (See
"Pressurization" on page
•
Enclosure cases spliced to gel-filled cable above ground can be left unpressurized except in flood areas
where static pressurization is recommended. (See

Ground the enclosure.
All pole-mounted doubler enclosures must be grounded. Install a No. 6 AWG copper ground wire between
the case mounting bracket farthest from the stub cable and a 5-foot ground rod driven into the ground.
Doubler enclosure stubs with shields bounded to a properly grounded main cable shield do not
require this additional ground wire. Noise due to ground loops could occur if the case is
grounded both places.

Ensure that the stub cable is properly bonded to the shield of the main cable if this is the only
means by which the double case is grounded.
The stub's screen should not be grounded nor should it be connected to other screens.
