The THA series have extra long straps that can be field-formed to give height adjustability and top flange hanger convenience. THA hangers can be installed as top flange or face mount hangers.
NEW! The THA218-2, THA222-2, THA418, THA422, and THA426 models have added nail holes in the straps to ease top flange installation and provide more nail hole options for meeting top and face nailing requirements.
Material: See table.
Finish: Galvanized, some products available in ZMAX®. See Corrosion-Resistance.
Installation:
Two different installation methods may be used:
Top Flange Installation - The straps must be field formed over the header a minimum of 2 1/2" for the THA29, 1 1/2" for the THA213 and THA413, and 2" for all others. Install top and face nails according to the table. Top nails shall not be within 1/4" from the edge of the top flange members. For the THA29, nails used for joist attachment must be driven at an angle so that they penetrate through the corner of the joist and into the header.
For all other top flange installations, straighten the double shear nailing tabs and install the nails straight into the joist.
Face Mount Installation - Install all face nails according to the table. Not all nail holes will be filled on all models. On models where there are more nail holes than required, the lowest 4 face holes must be filled. Nails used for the joist attachment must be driven at an angle so that they penetrate through the corner of the joist into the header.
