NOT RECOMMENDED for mast with a wall thickness less than 10 ga (.134) such as
Non-Penetrating Roof Mounts and Roof/Wall Mounts.
Once fine tuning is complete and all Clamp Bolts are equally torqued to 18 ft-lbs. in
accordance with 8000842 manual, then install the two M8 x 20 mm Hex Head Set Screws
supplied. Install one in each clamp half as shown in Fig. 1.0. Torque each M8 x 20 mm
Hex Head Screw to 15 ft-lbs. Repeat torque to insure 15 ft-lbs. has been reached on both
screws.
