BlazeFrame® Perimeter L-Bead

VINYL L-Bead with Compressible Foam

Creates an easy attachment that is attained with staples through the bead flange.

Application(s): Standard Wall, Chase Wall, Shaftwall

BlazeFrame® Perimeter L-Bead creates an easy attachment that is attained with staples through the bead flange. Multiple perforations along the 1-1/8" flange enhance strong compound adhesion and the raised shoulder provides for a flush finish. Rigid vinyl is rust proof, dent resistant and easy to field cut without distorting profile or leaving sharp edges and burrs.

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 Fire Stop Deflection Track Systems, BlazeFrame Perimeter L-Bead is UL 2079-fifth edition compliant. Provides joint protection for up to 1" with UL 2079 Class II or III Movement Capabilities at 80% compression.

U.S. Patent Number 11,725,401 and 11,486,150 on Perimeter L-Bead.
