EWP Hangers
THFI Face Mount I-Joist Hangers
The THFI is a face mount hanger designed to attach EWP I-joist members to
wood headers. The unique design of the THFI combines the installation ease
of a top mount hanger with the installation exibility of a face mount hanger.
Because the side anges extend to the top chord of the I-joist, web stiffeners
are not required. The THFI hangers also feature strategically placed Seat
Cleats
®
which lock the bottom ange of the I-joist to the hanger eliminating
the need for joist nails to be installed.
The innovative top ange alignment tabs with the holding cleats assist
the placing and alignment of the hanger prior to nailing by hanging onto
the header with holding cleats biting into the wood. If the alignment tabs
are not desired or a deeper height member is to be carried, the tabs can
be easily bent out of the way. Alignment tabs do not contribute to the
allowable design values of the THFI hangers.
