IN-CEILING INSTALLATION
Type: IC-2
Understanding the L-Bracket
Extensions
Designed to attach to the top and
bottom ends of the enclosure, the
L-Bracket Extensions (Part I) permit
the enclosure to be installed in ceiling
cavities with joist widths ranging
from greater than 17 ½-inches to 25
½-inches on center.
The L-Bracket Extensions (Part I)
are equipped with pre-drilled pilot
holes that align with pre-drilled
pilot holes in the enclosure. When
mounting, the L-Bracket Extensions
(Part I) should be centered between
the ceiling joists, with both sets of
pilot holes aligned. Once installed,
there should be a small space at
each end, between the L-Bracket
Extensions (Part I) and the adjacent
ceiling joists.
(Figure 14)
Note: For ceiling cavities with
joist widths that are greater than 17
½-inches but less than 24-inches, it
will be necessary to cut the L-Bracket
Extensions (Part I).
Measure the width
between the ceiling joists and cut the
L-Bracket Extensions (Part I) to a width
of 1.00-inch less than the measured
dimension. It does not matter which end
of the L-Bracket Extensions (Part I) the
excess material is removed from. The
reduced size will permit the L-Bracket
Extensions (Part I) to fit within the
narrower joist width, leaving a small
space at each end once installed.
