The installation of the truss is a muli step process where as each truss is set upside down on the bond beam and turned up individually using long sticks. The sticks are used as braces to temporarily hole the trusses upright. A long stick (rat run) is placed on the collar tie of each truss to stabilize the bottom and an angle brace is installed to keep it upright. On center dimensions are measure out on the rat run and the truss is plumbed up with the brace. This is a temporary measure until the ridge beam is installed. The rat run also acts as scaffolding in this scenario.
