Bogen TBCR Installation Manual

Model TBCR
TILE BRIDGE SUPPORT RING

Description

The Tile Bridge Support Ring (TBCR) is designed to offer additional
mounting support for a variety of installations involving clamping type
ceiling speakers.

Installation

SUSPENDED CEILING INSTALLATION

1. Remove the tile from the ceiling and put the TBCR on top of the ceil-
ing tile, aligning the ends of the TBCR rails as shown in the drawing.
2. Typically the ceiling speaker will be mounted in the center of the
ceiling tile.The support ring should be positioned in the center of the
rails and the ends of the rails flush with the sides of the tile for this
installation. The speaker can be mounted in other locations in the
ceiling tile by moving the ring and/or tile bridge assembly if desired,
however, care must be taken to ensure that the TBCR rails will still
be flush with the tile sides and that the ring portion will not
interfere with the suspension grid.
3. Use the ring as a guide to cut a hole in the ceiling tile.
4. Sandwich the tile between the TBCR and the speaker bezel and
tighten the speaker clamps. Complete speaker installation and
connections as directed in speaker's instruction manual.

NEW CONSTRUCTION - JOISTS EXPOSED

In new constructions, the TBCR can serve as a routing guide for the
speaker cutout when installed before the sheetrock is applied. It provides
a second benefit by stiffening the area around the bezel after speaker
installation.
A. For 16" Centers Joist Spacing
In 16" joist spaces (the outside distance of the joists must be no
greater than 17" and the inside spacing of the joists must be no less
than 14¾" in order for the rails to fit), the support ring must remain
in the center of the rails. Shifting the ring position may cause the
swing out clamps of the speaker to hit the joist and prevent it from
fully extending.
Note: Support Ring must be fully within the joist space for
the speaker to mount correctly. Also, check that there is
sufficient vertical space above the ring to fit the particular
speaker being used.
1. Remove the 4 breakaway tabs.
2. With the ring section attached, nail the TBCR in 4 places to the
bottom of the joists through the nail holes. (Two nail holes are
provided in each joist location. Pick the one that is closest to the joist
center.) The 24" center tails of the rails will protrude into the
adjacent joist spaces.
3. After the sheetrock is up and the hole routed, follow the speaker's
installation instructions to complete the installation.
