The beam clamp mounting system is designed to provide an easy and secure way
of mounting horn speakers to I-beams.

1) For easier installation, detach the horn base (flange) from the horn (refer to
the speaker’s instruction manual for directions on detaching the base).

2) Bolt the base [3] to the beam clamp [5] using the supplied bolt [1] and lock
washer [2].

A flange hole [4] is provided in the base of later model Bogen horn
speakers. For earlier model horns without this hole or non-Bogen horns,
drill a 3/8” hole in the base.

Two bolt lengths are provided. Use the longer bolt for mounting the cast
bases of Bogen’s 15W and 30W horns. Use the shorter bolt for the
stamped bases of the 5W and 7W horns.

NOTE: It is important to use the correct length bolt or

else the clamp or base will not seat properly.

3) Fasten the beam clamp assembly to the web of an I-beam and tighten the
clamp bolt [6] well to secure the horn’s mounting base in place.

4) Place the horn speaker onto its base, wire it, aim it at the desired area, and
tighten the wing nut to lock it in place.
