FWHFM Fire Wall Hangers for Face Mount Applications
The FWHFM hanger fastens to the wide face of a balloon framed SCL
column thereby eliminating the additive perpendicular-to-grain bearing
stresses in the wall top and bottom plates seen with platform framing.
The advanced design allows you to install the hangers before the
gypsum wallboard (drywall) is attached, allowing your project to be
completely framed-up and weather-tight before the gypsum wallboard
sheathing shows up on site.
Features and Benets:
• Face mount hanger design installs with nails
• Attaches to the wide face of columns
• Hanger web accommodates 2-plies of 5/8" gypsum wallboard
• Achieve full table loads with or without drywall installation
Materials: 12 gauge
Finish: Primer
Options: See Specialty Options chart on page 201
Patents: Pending
Installation:
• Install the face of hanger anges tight to SCL column/framing.
• The end of the truss/joist should measure 1-5/8" from the face
of the supporting column.
• The truss/joist should bear fully on the FWH 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 specied 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.
