align with the third set of holes in the Frames.
c. Position the upper Cross Braces to align with the next set of holes in the Frames and then
approximately every 8’ thereafter.
d. Attach all of the Cross Braces to both Tower Frames using two
3/8-16 x 0.750 Hex Head Capscrews in each side.
The Capscrews attach directly to a welded nut on the inside of the Cross Braces.
