Flying using Eyebolts
WARNING: As the legal requirements for flying change fom country to country,
please consult your local safety standards office befoe installing any product.
We also recommend that you thoroughly check any laws and bylaws prior to
commencing work.
The device can also be hung via 4 top-mounted eye bolts. Rear of back can has
mounting points for both M10 and 3/8 UNC threaded eyebolts.
Flying using Screwed Rod
The design also caters for a single point central hang via M10 or 3/8 UNC screwed
rod – made easy thanks to the slotted mounting saddle on the top of the back-
can. If required a safety wire can be attached to any of the M10 flying points.
To fit the back can to theaded rod support, first run a nut 50 mm (2") up the od
followed by two plain washers and then a locking nut (Nyloc). Hook the back can
on to the rod between the two plain washers. Once the nut has cleared the guide
slot the top nut can be locked down to secure.
Fitting the Loudspeaker Assembly
Mounting of the loudspeaker assembly to the pre-installed back-can is a one
man job thanks to the common sense design approach. One edge of the baffle
clips onto the steel box to hold it in place while the installersecures the assembly
in place. Connection is simple via terminal barrier strips inside the can, easily
accessible via 20 mm (0.79") and 29 mm (1.14") conduit knockouts on all five
sides of the can. Saving time and manpowerduring installation has been a
driving factor behind the design of the CMS 1201 system.
Baffle assemble can be hooked onto the back can with care.
