Head of Wall Deflection

SCAFCO Slotted Track and Seismic Drift Track are the industry preferred systems for achieving head-of-wall deflection, drift, and fire rating for interior and exterior walls. SCAFCO Slotted Track has met the movement and cycling requirements of ANSI/UL 2079, and is UL classified for 1, 2, 3 & 4 hour fire ratings in head-of-wall fire-rated joint systems.

SCAFCO Seismic Drift Track allows for lateral movement of the main building structure, while still accomodating head-of-wall deflection and fire ratings for interior and exterior walls. The Seismic Drift Track comes with an extruded metal insert that aids in the connection of the track to the main structure.

TTDS track-in-track deflection system is a two-piece assembly that accommodates deflection of exterior curtain walls and interior partition walls. The outer track is custom-made with a deeper leg and wider web width typically installed to the underside of the floor or roof deck.
