FWH Fire Wall Hangers
Continued on next page
Geometry Table
The Fire Wall Hanger is designed for attaching truss, I-joist, solid sawn lumber,
or engineered wood oor framing members to double wall top plates or minimum
2-ply 2x solid sawn header re rated wood frame walls. The advanced design
allows the installation of the FWH before the 5/8" gypsum wallboard (drywall)
is attached and permits the building project to be completely framed-up, and
weather-tight before the gypsum wallboard sheathing work starts.
Materials: 14 gauge
Finish: G90 galvanizing
Options: See Specialty Options chart on page 195
Codes: IBC, FL, LA
Patents: U.S. Patent No. 10,316,510
Installation:
• Install the face of hanger anges tight to stud wall framing.
• For typical installations, the FWH does not need to be installed at stud
locations. An increase in capacity can be achieved by installing the FWH
at a stud. See the Allowable Load Table on page 195.
• The end of the truss/joist should measure 1-5/8" from the face of the
supporting wall. See Figure 1.
• 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. See Figure 1.
• 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.
