Installed the 3/8" ceiling hooks into the ceiling joists to hold locking pulleys for the wing lift. Each hook/pulley is capable of holding 260 pounds which by itself exceeds the total weight of the wing. Speading that weight across 4 pulleys adds a considerable safety margin.
I also constructed the riveted aluminum sheet metal notebook handed out by Zenith at their open house in September 2013. Perfect for holding my Photo Assembly Guides.
Inboard ceiling hooks installed with locking pulleys in place.
