Product Overview
THA413 Adjustable Truss Hanger
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.
THA4x and THA2x-2 models feature a dense nail pattern in the straps, which provides more installation options and allows for easy top-flange installation.
Material:
See table
Finish:
Galvanized (G90)
Installation:
Use all specified fasteners; see General Notes.
The following installation methods may be used:
Top-Flange Installation — the straps must be field-formed over the header — see table for minimum top-flange requirements. 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 (Min.) Installation — install face nails according to the table, with at least half of the required fasteners in the top half of the header. Not all nail holes in the straps will be filled. Nails must have a minimum 1/2" edge distance. Straighten the double-shear nailing tabs and install the joist nails straight into the joist. The face-mount (min.) installation option accommodates conditions where the supported member hangs either partially or entirely below the header.
Face-Mount (Max.) Installation — install face nails according to the table. Not all nail holes in the straps will be filled except for the following models: THA29, THA213, THA218 and THA413. For all other models with more nail holes than required, the straps may be installed straight or wrapped over the header, with the tabulated quantity of face nails installed into the face and top of the header. The lowest four 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.
Uplift — lowest face nails must be filled to achieve uplift loads.
Options:
THA hangers available with the header flanges turned in for 3 5/8" (except THA413) and larger, with no load reduction — order THAC hanger.
