nels, check the enclosed bill of materials to
ensure that all parts and components are present and undamaged. Read all installation instructions first and
familiarize yourself with all parts and components. This is extremely important because parts
will become permanently damaged if they are installed incorrectly!
To help with identification, all parts are poly-bagged and labeled.

Basic Installation
Step 1
Establish an "X" and "Y" baseline on the
floor or ceiling following the diagram provid-
ed with your components. Baselines are
typically referenced off a structural building
element.
Step 2
Determine all hanger wire locations indexed
off the "X" and "Y" baselines. These
markings indicate where the hanger brack-
ets will be attached.
Step 3
Project each hanger location to the deck or
structural ceiling and attach wires, cables,
or rods with the appropriate fasteners.
Its very important that all wires are plumb
so as not to pull on the assembly. Bridge
or trapeze accordingly with appropriate
structural members.
Step 4
Attach the hanger brackets at the required
height using hanger wire, aircraft cable, or
threaded rods.

Step 5
Position one side of the Paired C
OMPÄSSO
channels on the floor, following their part
identifications. Using the reference dimen-
sions on the drawing, align the Paired
C
OMPÄSSO
Channels with the hanger wire
locations.
Step 6
Transfer the hanger wire locations to
the top of the Paired C
OMPÄSSO
Channels.
These markings indicate where each
hanger bracket will be attached.
Step 7
Snap the first channel onto its corresponding
hanger brackets.
Tip: Start at an intersection; if there is
no intersection, start near the middle of
the assembly.

Basic Installation Page 5 of 12
Step 8
If the installation is to form a circle, the
inside channel should be installed first.
Step 9
If the channels have intersection notches,
make sure they line up properly.
Step 10
Continue on, referring to the shop drawing
and adding additional hanger brackets
to ensure uniform spacing between the
channels. Page 6 of 12
Step 11
Connect channels by using splices to
join them.
Step 12
Use splice covers to cover the channel
joints. Splice covers can also be used to
cover any slight gaps or uneven field cuts.

Instructions
Basic Installation Intersection
Installation
Step 1
Align intersection notches as the paired
channels are snapped onto the hanger
brackets.
Step 2
Attach a hanger bracket to the face of the
notched C
OMPÄSSO
channel using number-10
by one-half-inch metal screws.
For a through-intersection, attach a hanger
bracket on each channel.
Step 3
Snap the intersecting channels onto the
hanger brackets and secure the channels
to maintain a good connection throughout
installation.
Page 7 of 12 Step 1
Corners are formed using notched and
scored trim for outside corners and pre-
mitered trim for inside corners.
To create an outside corner, bend notched
corner trim along the score to the desired
angle and slide a standard splice part way
in on each side.
Step 2
Slide the corner unit into place to join the
outer C
2
channels.
Step 3
To form an inside corner unit, start by snip-
ping the top and bottom flanges of an inside
corner splice at the center

both right and left end caps.
Step 2
Hook the lower lip of the end cap over the
bottom flange of the C

channel, then bend
the top tab of the end cap over the top
flange of the channel.
Step 3
Install the end segments.
Tip: Depending on design, the channel
ends may be aligned or offset. Refer to the
shop drawing for details on your specific
installation.
