INSTALLATION:
3.1. Remove handrails from Fortress OSHA Stair System, if installed, and set aside.
WARNING!
Use extreme caution on platform when handrails are removed.
3.2. Insert 1 1/2” square canopy posts into platform corner pockets with the holes oriented toward the platform. The
canopy corner post, the only one with holes on all four sides, must be in the corner where the two handrails will
connect. Orient the two canopy posts at 90° from the corner post so the holes are in line with the holes in the
corner post (FIG. 1).
3.3. Set canopy roof on canopy posts. Insert top of canopy posts into canopy roof corner pockets and tighten
corner pocket set screws (FIG. 1).
3.4. Insert 5/16”-18 x 3-1/2” button head socket cap screws, 5/16” flat washers, and 5/16”-18 locknuts as shown
(with the locknuts on the inside) to attach handrails to the canopy posts. Tighten all fasteners securely (FIG. 2).
3.5. Install 1/4” x 1” pan head Phillips self-tapping screws through the existing holes in the platform corner pockets
into the 1 1/2” square canopy posts (FIG. 2). Pre-drill 1/8” pilot holes in the canopy posts if needed.
3.6. Make sure all fasteners are in place and tightened securely. Regularly check and tighten
fasteners as needed.
