The PF series hangers have been designed to accommodate collated 0.148" x 1 1/2" nails as well as 0.148" x 3" nails. The PFB and PFDB have dome-shaped joist nail holes that guide nails into the proper installation angle. The design also features a folded seat that raises the 2x joist very slightly above the seat radius to enable a tighter connection to the back of the hanger. For saddle hangers, PFDB and PFDSB are for solid sawn lumber carrying members, and PFDL is for LVL carrying members.
Many of these products are approved for installation with Strong-Drive® SD Connector screws.
