Simpson Strong Tie Unveils New DG Fire Wall Hanger Series

Simpson Strong Tie, the industry leader in engineered structural connectors and fasteners, rolled out their new DG Fire Wall Hanger Series last week.

The three models of top-flange hanger connect floor joists to the wood wall with enough space for two layers of 5/8” drywall installation later. This allows the completed fire wall assembly to remain continuous from floor to floor. Each of the three models of fire wall hangers have been tested in-line with ASTM E814 standards to verify no overall reduction in the two-hour assembly rating. Additionally, each DG hanger received F(flame) and T(temperature) ratings for either or both sides of the wall.

The new series is ideal for Type III multi-family, multi-level building construction, a solution that couldn’t come at a better time given the recent rise in popularity of Type III multi-story wood construction.


It’s essential that “large, multi-family buildings are constructed with the safest, strongest, most rigorously tested products,” said Sam Hensen, VP and GM of Connectors at Simpson Strong-Tie.


Key features of the DG fire wall hangers include:

  • A gap wide enough to install two layers of 5/8″ drywall
  • The ability to frame the entire structure before starting drywall installation
  • Published listing by Intertek for the DG series in a 2-hour wood fire wall
    • Including F (flame) and T (temperature) ratings per ASTM E814 testing
  • No need for additional restraint against rotation of the wall top plates
  • Can be used on 2×4 and 2×6 walls
  • May be used on both sides of a 2×6 wall
