Opening the conduit hole
If you need to bring the facility cables in through the side of the arm, open a conduit hole in the arm for either

To open the conduit hole, see Figure 38 on page 66 and do the following:
1. Locate the dimple on the side of the arm.
2. Drill a 3/8 in. (10 mm) pilot hole through the dimple.
3. Enlarge the pilot hole to 1-7/64 in. (28 mm) for a 3/4 in. conduit connector or to 7/8 in. (22 mm) for a
1/2 in. conduit connector.
4. Return to step 2 of Installing the wall-mount arm on page 62.
