The THA series extra long straps allow full code nailing and can be field-formed to give top flange hanger convenience. Designed for 4x2 floor trusses and 4x beams. Top flange installations, straighten the double shear nailing tabs and install the nails straight into the joist. For face mount installation, install all face nails according to the table. On models where there are more nails 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. Minimum carried member 2x4 to 4x10.
