The PFDB hangers are top-flange saddle hangers for post-frame construction. They have dome-shaped joist nail holes that guide nails into the proper installation angle. Their design features a folded seat that raises the 2x joist slightly above the seat radius to enable a tighter connection to the back of the hanger. The solid, one-piece top flange allows for accurate and fast installation. PFDB Galvanized Post-Frame Saddle Hanger for Double 2×4 (Pack of 1200).
