The THASR/L hangers combine the height adjustability of THA hangers with field skewability, offering maximum flexibility for the installer, and eliminating the need for special orders. Shipped at 22 1/2° right or left, the THASR/L hangers can be field-skewed from 22 1/2° to 75° (up to 85° for the THASR/L29 and THASR/L29-2).
The THASR/L29, 29-2 and 422 are replacing the former 218, 218-2 and 418 versions.
The THASR/L single- and two-ply versions have straps 9" tall. The 4x version has 22" straps to fit more parallel-chord truss applications.
The versions have only one acute side bend line to ease design and installation.
Joist fasteners are only required from one side for skews greater than 22 1/2°.
Rated for installation with either nails or Strong-Drive® SD Connector screws.
Galvanized. Some products available in ZMAX® coating. See Corrosion Information.
Use all specified fasteners; see General Notes and the table below.
Product is factory-skewed to 22 1/2° and may be field-skewed from 22 1/2° to 75° (up to 85° for the THASR/L29 and THASR/L29-2). See Installation Sequence in the image gallery for skews greater than 22 1/2°.
For top-flange installations, the straps must be field-formed over the header a minimum of 2".
THASR/L29 and THASR/L29-2 — For installations where either strap cannot be field-formed over the header, install the strap(s) vertical and fill all holes. Loads must be reduced as noted in the table footnotes.
THASR/L422 — For face-mount installations, install the carrying member fasteners into the lowest holes.
Allowable Loads for Installation with Strong-Drive® SD Connector screws
Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
Wind (160) is a download rating.
Minimum carried member heel height shall be 4 1/2".
Heff is the distance from the top of the hanger seat to the top of the carrying member.
For tabulated top-flange installation loads, the straps must be wrapped over the header a minimum of 2". Allowable downloads for the THASR/L29 and THASR/L29-2 with one or both straps installed vertically (all holes filled) are 90% of the tabulated downloads for skews greater than 22 1/2° and 85% of the tabulated downloads for 22 1/2° skews. Allowable uplift capacities are 100% of the tabulated uplift load capacities.
Allowable downloads for 75°–85° skews with one or both straps installed vertically (with all holes filled) shall be limited to 75% of these loads.
