Ceiling Brackets
Special brackets are supplied with the CV versions of the PRi speakers that make it easy to mount them in a suspended ceiling. The bracket rests on top of the ceiling grid so the weight of the speaker is supported by the grid, not the ceiling panel. The bracket has a “foldable” design, shown on the left below, that makes it easy to maneuver the bracket through the mounting hole.

In this illustration the ceiling grid is shown without the panels.
Once the mounting hole is cut in the ceiling panel pass the folded bracket through the hole and pivot it into its normal shape as shown below on the right. Then extend the rails so they rest on the ceiling grid. Set the bracket so the flanges that extend down from the arcs surround the installation hole. Then connect the speaker and clamp it in place as in a regular installation.
NOTE: Boston Acoustics strongly recommends the use of safety cables in all installations. This is particularly important when the PRi speakers are installed in suspended ceilings. Attach one end of the security cable to the tab on the back of the speaker and fasten the other end to a strong structural element of the building.
The ceiling bracket can also be used in dry wall ceilings. Cut the standard required hole for the speaker in the drywall. Insert the collapsed bracket through the hole and expand it into normal shape. The orientation of the extendable rails is not important. They can remain fully retracted. If the installation location is very tight the ex- tendable rails can be removed so the center section will serve as a plaster ring.
