FOR MOUNTING SPEAKERS
Step 2:
Attach the AJ-1524 adjustable u-bracket to the cross
arm using the two ¼-20X1 hex screws, nuts and
washer on the four outer holes of the cross arm. On
the
15” wide or near 15” speaker use only the four through
holes on the cross arm (Figure 2). Make sure to place
the spacer clip in between the inner bracket and the
cross arm. Do not permanently tighten. Adjust the AJ-
1524 to the size of the speaker, add at least ½” gap for
the gaskets. Capture the overlap of the AJ-1524 inner
and outer bracket using two or four ¼-20X2.5 hex
bolts, nuts and washers on the slots of the cross arm
(Figure 3). Tighten all bolts permanently.
