7.2.1.2 019ALU Crossarm
Attach the 019ALU crossarm to the mast as shown in FIGURE 7-9.
2. Position the middle NU-RAIL so that it rests on top of the bell reducer.
Orient the 019ALU in an East/West direction, with the 3/4 inch NU-RAIL
facing East and tighten the set screws. If the 019ALU is used with the 025
Crossarm Stand, orient the 019ALU North/South, with the 3/4 inch NU-
RAIL facing South.
3. Install the lightning rod to the mast as shown in FIGURE 7-9. Loosen the
two screws on the lightning rod mounting bracket. Position the mounting
bracket 2 in down from the top of the mast and tighten both screws evenly.
Make sure the lightning rod set screw is tight.
7.2.2 Gill Radiation Shields (41303-5A, 41003-5, 41005-5)
1. Attach the radiation shield to the tower leg, tower mast, or CM202,
CM203, CM204, or CM206 crossarm with the U-bolt and nuts provided.
If attaching to the tower leg or mast, place U-bolt in the radiation shield’s
side holes. If attaching to a crossarm, place the U-bolt in the radiation
shield’s bottom holes.
