• Re-insert the tilt-locking bolt and thread it into through the tilt
arm and the moving cam and tighten it firmly using the 5 mm
hex wrench.
Installing redundant safety anchors
Attention: When correctly installed, the Wall Bracket and the
Horizontal Mounting Bracket are designed to safely support the
CT28 speaker enclosure under normal conditions. However,
connection to an external anchor point using a steel wire rope
safety bridle is strongly recommended in any installation where
people could pass beneath or near the loudspeakers and may
be required by local or national codes in installations in public
places. If you intend to install a secondary safety bridle anchored
directly to the enclosure, it is recommended that you use two of
the M5 rigging points on the top of the CT28 enclosure for this
purpose.
In most cases of wall mounting a single CT28 enclosure, the use of
a steel wire rope safety bridle will provide sufficient redundant safety.
Carefully review the third-party manufacturer's documentation to assure
that the bridle and all its components are certified for the proper Safe
Working Load with the required Factor of Safety. The length of the
bridle and termination on the opposite end will obviously depend on the
requirements of the structure to which it will be anchored.
It will be necessary to install two eye bolts in the rear M5 rigging points in
the place of the M5 × 25 mm screw supplied with the speaker enclosure.
Only a forged steel eye bolt with a collar or shoulder, certified for the
proper Safe Working Load with the required Factor of Safety at its
minimum load angle can be used.
Important: For permanent or semi-permanent installation,
the use of medium-strength thread-locking compound is
recommended on all user-installed screws.
