Fixed Width U-Bracket series

Installation Instructions

The UB-263-12 U-Bracket is a mounting bracket
that attaches loudspeakers to a wall, deck,
ceiling, or balcony and provides one axis aiming
feature.

Warning:

Mounting and/or rigging loudspeakers requires
experienced professionals.

loudspeakers can result in property
damage, personal injury, death and/or
liability to the installing contractor.

Note to Contractor: Due to the wide variety of

wall structures, materials and methods, the
contractor should exercise good judgment in
selecting the proper mounting area and
hardware. Do not rely on drywall, acoustic tiles,
etc. to support the weight of any loudspeaker.

To assure a trouble free installation, read through
and follow these instructions carefully before
beginning. If you have doubts about the integrity
of the structure you are mounting to, or you are
not sure about the proper hardware to use, consult
a structural and/or hardware specialist. The
structure should be capable of supporting 5 to 10
times the actual weight of the speaker. The use of
a back up safety system, such as a safety cable, is
highly recommended. Standard safety cables are
available from stock.
