Stayed up until 6am getting my wiring done before drywaller came at 8am (needs a bit of tidying up)
The mandatory drywall lift pic:
Insulated plus clips and track. I also attached a rigid boot to the end of the two flex returns.
Supply duct was too tight to track so I simply pulled the flex through the opening
These are the screws he used for the first layer. He initially tried the 1 1/4" but they weren't holding so he went with these. Do these look ok for 5/8" OSB into hat channel????
