5.9. TWO-LINE RAIL CORNER TURN
There are four special closures available for filling the space between two ramps in a corner turn
configuration: Two-Line Rail for a 5’ x 5’ platform; Picketed Guard for a 5’ x 5’ platform; Two-Line
Rail for a 6’ x 6’ platform; and Picketed Guard for a 6’ x 6’ platform. Corner turn closures for a 5’ x
7’ and 5’ x 6’ platforms are uncommon so must be ordered as customs for the specific
arrangement.
5.9.1. Install the 2” x 2” angle post (not already attached to the platform), two-Line Rail, or
picketed guard in the open platform corner. Align the bottom of the post with the
bottom of corner pocket, then tighten the set screws securely. Refer to SECTION 4.6 for
additional details on securing the post.
5.9.2. The barrier and midrail of a two-line corner turn are installed in the same manner as a
closure at an upper landing. Refer to SECTION 5.3, ‘TWO-LINE RAIL BARRIER AND
MIDRAILS’, and complete the steps described to connect both Frames to the 2” x 2”
angle post in the corner. FIG. 5.36 shows the assembly at this stage.
