the desired angle, and
lock in place with the
attached ball-lock pin.
To give further explanation, Holes A-D are used for down-tilt and holes E-H are used for
up-tilt. Hole A is used for 0-degree angle, and also for multiples of 20 degrees above this
(20, 40, 60, 80 degree down-angle). Hole B is used for 10 degrees, and multiples of 20
degrees above this (10, 30, 50, 70, 90 degree down angle). Similarly, Hole C is used for 5
degrees and multiples of 20 degrees above this (5, 25, 45, 65, 85) and Hole D is used for
15 degrees and multiples of 20 degrees above (15, 35, 55, 75). Holes E-H apply in a
similar way for up-tilt.

of the enclosure until the two ¼” diameter locking-pin
holes line up. Insert the two ball-lock pins into the
holes to lock the bracket in place. IMPORTANT: DO
