BLAZEFRAME (DL 2) deep leg
Profile with two solid legs with firestop on both sides. Composite Firestop Deflection Track System for use in fire-rated wall assemblies. Two solid legs supporting “free floating” studs.
Composite Firestop/Framing for use in fire-resistant joint systems in or between fire-resistance-rated walls and floor/ceiling or roof/ceiling assemblies. Many assemblies can also be used in smoke barriers with tested air leakage (L ratings) well below the code defined maximum of 5 cfm per linear foot.
When used in conjunction with BlazeFrame Perimeter L-Bead, DL 2 is UL 2079-fifth edition compliant. Provides joint protection for up to 1" with UL 2079 Class II or III Movement Capabilities. Two solid legs supporting "free floating" studs per listed assemblies in UL Fire Resistance Directory. A 2mm thickness of cured intumescent material adhered to metal profiles provides air and smoke seals. When exposed to heat above 375 degrees Fahrenheit, the intumescent material expands up to 35 times its size. This provides protection from heat and flame passage during a fire event..
