Installation Instructions for Swivel Beam Clamp
The SBC3-8-CA-20 is a load rated overhead swivel beam clamp with
a 20” cross arm for mounting and suspending speakers. It is used to
mount speakers with the AJ-1524 adjustable U-Bracket, stand yoke
mounts or as a suspension arm when eyebolts are installed. The
cross arm provides a rotation of 360° horizontally.
Warning:
Mounting and rigging audio equipment requires experienced
professionals. Improperly installed audio and video
equipment can result in property damage, personal injury,
death and/or liability to the installing contractor.
Important:
Due to the wide variety of overhead structures, rigging materials
and rigging methods, these instructions assume that the installing
contractor/installer will exercise good judgment in selecting the
proper suspension points, hardware and mounting area.
As a guide, the installation, when completed should be
capable of supporting at least 5 times the actual applied
load. Do not exceed the rigging system’s working
load limit of 300 Lbs. Use only Grade 8 hardware or
load rated hardware to ensure a safe installation.

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.
