5.4.7. Install a 5/16″-18 x 1″ hex bolt through a 5/16” flat washer and the upper hole in the
angle post into the 5/16”-18 round threaded insert, then tighten all fasteners securely
(FIG. 5.6).
5.4.8. Test to ensure elbow is properly secured and attached. If needed, tighten internal set
screws to secure more rigidly.
5.4.9. Once the top rail is in place install the 1-1/2” x 2” curb. Locate a platform closure bracket
and bolt the short leg of the bracket to the lowermost hole in the ramp handrail post
using a 5/16″-18 x 2-1/4″ hex bolt, 5/16″-18 nut and 5/16” flat washers. Orient the
bracket so the long leg is on the same side as and parallel to the platform post then
tighten lightly (enough to hold the bracket against the post but still allow it to rotate)
(FIG. 5.7).
