Offsets:
If any offsets are necessary in the vertical system, an Offset
Support (OS) should be installed directly above the upper elbow
of the offset. Install by attaching the Offset Support Band to the
pipe with two #8 x 1/4” sheet metal screws (minimum) and
secure the Offset Support Straps to surrounding structure (see
Fig. 5).
Ceiling Support (CS) (used in flat ceiling installations) comes
with a Support Plate and a Support Collar. Install it by screwing
the Support Plate to the top of the properly framed ceiling joist
opening, using screws provided. A round Trim Plate (TP) is
attached to the ceiling, using screws, to provide a finished
appearance once installed (see Fig. 3).
The Cathedral Ceiling Support (CCS) may be used in pitched or
flat ceiling installations and comes with a Support Collar and
adecorative two part square Trim Plate. Install by inserting the
support box down through the framed joist
opening (end with
round hole first) in the ceiling. Using tin snips, cut the corners of
the open end of the box such that the sides can be folded down
over the top of the joist framing members. Nail the folded
sidesto the top of the framing (see Fig 4).
