Exterior Slotted Track
True-Action™Slotted Track is the industry preferred system for achieving head-of-wall deflection and fire resistance for interior and exterior walls. It meets movement and cycling requirements for ANSI/UL 2079 and is UL Classified for 1, 2, 3, and 4 hour fire-resistant ratings in head-of-wall fire-rated joint systems.
- AISI North American Specification [NASPEC] S100-07 with 2010 supplement.
- IBC 2006, 2009 & 2012 Compliant
- Gross properties are based on the full section away from flange slots.
- Net area is based on the section through the flange slots.
- Weight is nominal weight of the gross section, not reduced for flange slots.
- For effective flange widths, the compression flange (before local buckling) is taken as the portion of
the flange between the web and the slot (the slot and any steel beyond the slot is considered absent). - The tension flange is taken as the net flange at the slots.
- Cold-work of forming has not been considered for effective properties.
- Multiple UL Head of Wall Deflection System Ratings
