A. Install 2 x 6 cross braces between the rafter tails, directly
above the cable holes in the bay/bow head board.
B. Install the cable clamps directly above the T-nuts where
adequate support is available. Holding the clamp parallel to the
up-running cable, drive the #12 x 3-1/4" square screws partway
into the mounting surface using a #3 square drive bit.
C. Run the cable up through the bottom of the cable clamp.
Hold the cable up tight above the clamp and drive the two
center clamp screws all the way in to lock the cable in place.
Drive in the remaining #12 x 3-1/4" square screws all the way.
Note: Make sure all 4 screws are driven in at maximum
torque. Additional tensioning may be done with the nuts
on the opposite end of the cable at the bottom of the bay/
bow unit.

A. Install 2 x 6 cross braces between the rafter tails, directly
above the cable holes in the bay/bow head board.
B. Remove the cable from the bay/bow unit.
Measure the distance from the bottom of
the cable clamp to the bottom of the header
plus 3/8" head clearance (A dimension).
Measure the height of the unit from the top
of the head board to the bottom of the seat
board (B dimension). Add "A" to "B" to get
the correct length of cable hanging from the
bottom of the cable clamp. Insert the cable
end through the round hole of the cable
clamp. Ensure the correct length of cable
is hanging below the bottom of the cable
clamp. Tighten the two cable clamp corner
screws. Insert one screw into each of the
center holes in the cable clamp, and tighten
to fully clamp the cable in position.
Note: Support cables are installed in factory assembled
bay and bow combinations.
