Great thread! My trapping was built on to the outside edge of inside out walls so the implementation is a little different, but they do share many of the concepts.
The popular frame with holes, made from 1x6 in this case.
The fabric covering will be stretched across the face between a pair of 1x2s. The small posts along the sides of the frame are to secure the 1x2s.
The frame fits floor to ceiling, and edge to edge on the front splay walls. It was tapped into place, then screwed into the frame of the walls and the rafters in the ceiling above.
The holes covered with bits of scrap.
Screws were placed inside the cavity to maintain the airspace behind the trap, the two layers of oc703 placed within.
Insulation filling the frame.
