FWHBP Fire Wall Hangers for Beams and Purlins
MiTek has expanded the FWH Fire Wall Hanger series to include the
higher load carrying capacity FWHBP, the Fire Wall Hanger for Beams
and Purlins. The FWHBP transfers the load into the supporting wall thru
bearing on the top plates and directly attaching to the stud pack or post
below. As with the FWH hanger, the advanced design allows you to
install the hangers before the drywall is attached, allowing your project
to be completely framed-up and weather-tight before the drywall
sheathing shows up on site.
Materials: 12 gauge
Finish: Primer

FWH hangers are tested per ASTM E814 standards. When installed on one
side of a maximum 2 hour fire-rated wall assembly, the penetration of
the MiTek FWH Fire Wall Hanger through the gypsum wallboard will not
reduce the fire resistive rating of the 2 hour fire resistive assembly.
