brackets (C and K) are aligned with the inside mating surface of each vertical channel of the ladder

Install a flange bolt (D), and secure with a flange nut (G). Tighten hardware to the recommended
torque specifications. See

5. Working down from the starter brackets (C and K), and in alignment, install a ladder standoff bracket
(H) at every horizontal seam or 32 in. from the previous installed bracket. Install a flange bolt (D) and
a flange nut (G), securing each ladder standoff bracket (H) to the sidewall.
NOTE: Installing a plumb line to the starter bracket will help keep each bracket aligned evenly.
