For alignment control between a roof truss and nonbearing walls; the 1 1/2" slot permits vertical truss chord movement when loads are applied.


  • 18 gauge (43 mil)


  • Galvanized (G90)


  • Use all specified fasteners; see General Notes.
  • Use STC or DTC depending on required loads. STC, installed with DS drywall stop, helps prevent fasteners tearing through the ceiling drywall (see installation illustration).
  • Use STCT where truss or rafter is separated from the top plate of the nonbearing wall.
  • Install slot nails in the middle of the slot.
  • Products not intended for floor applications due to the frequency of floor joist deflections and potential for squeaks.
