Make a Joist Jig, cont'd
Construct a simple jig with a 5 x 12-in. piece of plywood and a scrap 2x4 cut to the width of your joists. Align the 2x4 to your layout line. Tack the plywood to the top of the ledger, making sure it’s tight. Place the joist hanger around the 2x4 and nail 16d galvanized nails through all the holes into the ledger board.
