Abstract
An improved flute plug for a head-of-wall assembly for fire rated wall construction beneath a fluted deck or ceiling. The improved flute plug can be friction fit within individual flute voids that run over the top of the header track. The improved flute plug can include a single piece pre-bent steel profile with fire stopping material attached thereto or contained therein. The fire stopping material can be oversized so that it will compress into the flute void over the top of the header track. The compressed fire stopping material can provide a seal against fire, smoke and/or noise through the fluted deck voids.
