CORNER BLOCKS 45° & 90°

• Used to guide up to 1-3/8” diameter cable on inside or outside

corners.

• Offers a bending radius of 23” (584 mm).

• Mounts on Pole Bracket GMP # 70372.

INSTALLATION PROCEDURE

1. Install Pole Bracket GMP #70372 by ratcheting until a tight fit to the
pole. Attach the safety clip to the messenger strand after unit is at­tached to the pole.

2. Slide the Corner Block center tube over the axle of the Pole Bracket.

Insert the safety pin, attached to the top of the block by lanyard into
the axle’s hole closest to the block. The pin prevents Corner Block
from falling off the mount and allows the block to swivel with the cable.

3. Loosen both knobs at top of the block to loosen the cable retaining
rollers.

4. Set up the cable retaining rollers approximately ¼” above the cable to
retain cable on Corner Block’s rollers.

5. Reverse the installation procedure to remove the Corner Block.
