Thanks for the link, JP! I was looking at that combo setup myself but I couldn't figure out what nails/staples that the medium gun used while in the HD store.
Do you glue the frames as well?
Do you shoot a fastener through the end bar into the top bar (horizontal) or just nail down through the top bar and bottom bar?
I use two staples per connection top down, side through top for top bar/side bar connections, same on bottom bar/side bar connections.
I don't use glue on the frames, my preferance.
Hope that helps.
