3 CABLE CLAMP INSTALLATION (continued)

C.When the bay/bow unit is being installed, thread the threaded end of the cable through the "T" nut, down the length of the bay/bow unit, and out the drilled hole in the seat board. Place a washer and two hex nuts on each cable end.

Note: The interior mullion cover can easily be removed for this purpose and must be reinstalled when installation is complete.

HEADER MOUNT OF CABLE CLAMPS

This method may only be used if the projection of the bay/bow is 18" or less. Use the Cross Bracing method if the projection of the bay/bow is more than 18".

Note: Be sure that the cable clamps are secured to a solid structural member - header, sill plates or wall stud. If the structural member or cable clamps are not securely attached, they may loosen during or after installation causing the bay/bow unit to sag.

A. Install the cable clamps. Drive the #12 x 3-1/4"

square screws part way into the mounting surface

using a #3 square drive bit.

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 window.

A.Tighten the top hex nut on both cable ends. Using a 3/16" wrench or socket, hold the cable end in position while tightening the top hex nut with a 1/2" wrench or socket. This will keep the cable from twisting as the hex nuts are tightened with a wrench.

B.Secure the seat board and head board by using 10d finishing nails or 2-1/2" long screws on 16" centers; nail or screw through the head board, seat board and shims into the rough opening.

C.Remove the temporary bracing. Check the window for level, plumb, sash reveal and operation. Readjust, if needed.

Note: Be sure to use the temporary support when readjusting the nuts.

D.Tighten the locking (bottom) nut on both cable ends and remove the temporary support once the final position is found.

DO NOT cut the threaded end off the cable as this will prevent future adjustment should it be needed.

E.Installation of knee braces is recommended to help support the weight of the bay/bow unit. Weight calculations must take into account the weight of the items that may be placed on the seat board of the bay/bow unit. Knee braces are required if the upper roof/framing members cannot support 1,300 lbs. or more.
