4.7. INSTALL PLATFORM TWO-LINE RAILS AND PICKETED GUARDS
4.7.1. Platform two-line rails and picketed guards are installed in the same manner.
Depending on the configuration, refer to FIGs. 4.11 and 4.12 as needed.
4.7.2. Pre-assemble the platform two-line rail or picketed guard for both sides of a straight
configuration and the “first″ handrail of a turn configuration as described in SECTION 4.
Make sure the angle posts (attached to guards, midrails, and or barriers) are oriented on
the same side with respect to the top rail or barrier or midrail, and are pointing outward
as shown (FIG. 4.12).
4.7.3. For the “second″ rail or picketed guard in a turn configuration, only assemble one angle
post as described above, paying attention to how it will connect to the “first″ handrail so
the angle post will be oriented correctly.
4.7.4. For straight platform configurations and the “first″ two-line rail or picketed guard on a
turn platform, drop the platform two-line rail or picketed guard into the corner pockets.
Align the bottom of the angle post with the bottom of the platform corner pockets.
4.7.4.1. Securely tighten the 3/8”-16 headless socket set screws on the inside of the
platform and below the platform deck (FIG. 4.11).
4.7.5. For the “second″ two-line rail or picketed guard on a turn platform, insert the angle post
into a corner pocket at 90° from the “first″ rail. Align the bottom of the angle post with
the bottom of the platform corner pockets and tighten the 3/8”-16 headless socket set
screws on the inside of the platform and below the platform deck securely.
