d.Take two frame-to-base bolts (B) from the hardware kit and place a washer (C) on each. Insert the bolts through the upright support mount, gasket, and base. Make sure that the front mount is adjacent to the crossbar weld, but not on top of the weld. See Diagram 4. Attach a lock nut (D) to the opposite end of each bolt. Hold the lock nut with the socket wrench while you firmly tighten the bolts with the hex key (G) provided.
Important: Perform the following step on one stair arm at a time.
