7) Position the inside and outside handrails in place, as shown in Figure 24. To ensure proper
alignment of the assembly, temporarily install hardware through the mounting holes in the handrail
brackets and the stair brackets.
On steps where a handrail bracket is attached, you will have to use the following hardware to
attach the stair treads through the brackets: 5/16” x 2.5” Socket Head Cap Screw (49), 5/16” Flat
Washer (34), 5/16” Nylon Washer (33), 5/16” Flat Washer (34), 5/16” Lock Washer (35), and a
5/16” Hex Nut (36), see Figure 19.
Next, be sure that the mounting plate for the Middle Stair Support (48) and the Step Bracket
Anchor (16) are flat against the concrete deck. Mark the hole locations for the concrete anchors in
the base of the middle stair support and the step bracket anchor.
Remove the hardware connecting the top ladder brackets to the lower stair assembly. The
handrails will also need to be removed. Move the stair assembly out of the way so that the
concrete anchors can be installed.
Drill the 3/8” diameter X 2” deep holes for the concrete anchors for the Middle Stair Support and
the 1/2” X 2” deep holes for the Bottom Ladder Brackets in the locations previously marked out.
Follow the instructions on page 30 for inserting the concrete anchors into the deck.
Place the stair assembly back in position over the installed concrete anchors. Attach the following
hardware to the concrete anchors, but do not fully tighten: Nylon Washer, Flat Washer, Lock
Washer, and a Hex Nut.
Reattach the stair assembly and the handrails. After all hardware has been attached, go
through and make sure that all hardware is tightened securely.
