SUPPORTING THE WINDOW
B. Remove the temporary bracing. Check the window for level, plumb, sash reveal and

Note: Be sure to use the temporary support when readjusting the hex nuts.
C. Remove blocking from under the seat board.
D. Tighten the locking (bottom) nut on both cable ends and
remove the temporary support once the nal position is found.
DO NOT cut the threaded end o 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. If the upper roof/framing
members are not capable of supporting 1,300 lbs. or if more
than 500 lbs. will be put on the seat board, knee braces must be
used in addition to the cables.
