FWAN Foundation Wall Anchor
MiTek’s FWAN-TZ Foundation Wall Anchor is designed to transfer
in-plane and out-of-plane foundation wall loads imposed by soil
through the joist/blocking into the oor diaphragm. The unique
design allows for installations that straddle the joist/blocking
eliminating bending stresses in the rim board that result from
offset installations.
The FWAN-TZ offers two methods of installation:
1. Centered Installation
• Compatible with joist/blocking up to 3-1/2" wide
• Highest load capacities for transfer of out-of-plane
loads into oor framing
• Rim board splices allowed anywhere along the wall
2. Offset Installation
• Installs in the space between the joists/blocking
• Out-of-plane loads are transferred thru the rim board
into the oor framing
• Offsets up to 4"
Materials: 16 gauge
Finish: G-185 galvanizing
Codes: IBC, FL, LA
Installation:
• Centered Installation – Fill only triangle holes when nailing
to the rim board.
• Offset Installation – Fill only diamond holes when nailing
to the rim board.
• FWAN-TZ must be installed tight to the outside face of
the rim board.
• Minimum sill plate thickness is 1-1/2".
• Offset Installations require that the FWAN-TZ be installed
within 4" of the joist/blocking.
• For Offset Installations, install with two narrow tabs against rim
board. Splices in the rim board are not permitted in the space
between the joists/blocking where the FWAN-TZ is installed.
• The designer must specify the anchor bolt size, spacing and
embedment necessary to transfer the foundation loads into
the sill plate. Stresses in the sill plate must be considered
when determining the maximum spacing of the anchor bolts.
