Chapter 7: Roof Assembly

Determine the correct orientation of the center collar in relation to any stairs or conveyor systems. Each

half of the center collar (A) has drilled holes for the installation of the cap plate and side plates that will be

installed later. For this procedure, each half of the center collar needs to sit securely on stands or suitable

blocks, allowing plenty of room to access the bolts on the bottom side of the assembly.

1. Locate each half of the center collar (A), and install the center collar splice plate (D) to the inside por-

tion on the center collar.

2. Install flange bolts (E) and flange nuts (B) to the six center holes (H) located on the center collar

splice plate (D).

NOTE: The remaining open holes along the outside edge of the center collar splice plate (D) will be

used when installing the A-frame rafters to the center collar (A).

3. Install the second center collar splice plate (F) to the underside of the center collar (A), and install

flange bolts (C) and flange nuts (G).
