CROSS BRACING MOUNT OF CABLE CLAMPS

A.Install 2" x 6" cross braces between 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 drive screws part way 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, locking the cable in place. Drive the remaining #12 x 3-1/4" square screws all the way.

Note: Make sure all four 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.
