FWHH Heavy-Duty Fire Wall Hangers
The MiTek FWHH Heavy-Duty Fire Wall Hanger is designed
to support beams and purlins at header locations. The higher
capacity of the FWHH is achieved through top ange bearing
along with added face and beam/purlin nailing. 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
Options: See Specialty Options chart on page 199
Installation:
• Install the FWHH hanger anges tight to the face of the header.
• A minimum 2-ply 2x10 header is required for proper installation.
• The beam/purlin should bear fully on the FWHH seat with a gap
no greater than 1/8" between the end of the supported member
and the hanger.
• Gypsum Wallboard Installation - Use the FWH-T template to slot
cut the gypsum wallboard. See FWH-T Template Sequence. Slide
the gypsum wallboard into position and fasten to the framing
members meeting the minimum requirements specied by code.

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.
