I need to insert a piece of 2x4 in between two joists (actually the bottom chords of two parallel trusses). The 2x4 will be perpendicular to the two joists and fit right in between and it's bottom is to be flushed with the joists.
The reason I need to do this is to attach the metal bracket for the track at the ends of a garage door. The track is parallel to my joists and does not reach either one so I am putting in a perpendicular piece so it can be mounted to. I need to do this in four places (two garage doors, two brackets each).
What is the best way to secure this piece of wood to the two joists?
(1) Just cut to fit between the two joists and hammer in 8d nails from the other side, through the face of the joists into the ends of the new lateral member.
(2) Use Simpson's 2x4 joist hangers or metal angles.
(3) Use a 2x6 and notch both ends, so that the longer section sits ON TOP of the two joists, where the shorter section fits in between. Apply the nail from the top through the top of the joists.
