HU314-2 Concealed Flange Hanger
HU/HUC hangers may be installed on a masonry/concrete wall as described below. Additionally, HU hangers with one flange concealed may be installed similarly.
HU and HUC products are heavy-duty face-mount joist hangers made from 14-gauge galvanized steel.
The HUC is a concealed flange (face flanges turned in) version of the HU.
HU is available with both flanges concealed, provided the W dimension is 2 5/16" or greater, at 100% of the table load. Specify HUC.
HU is available with one flange concealed when the W dimension is less than 2 5/16" at 100% of the table load. Specify as an 'X' version and specify flange to conceal.
For any HU or HUC shown in this catalog, the user may substitute all face nails with 1/4" x 1 3/4" Titen® 2 screws (model TTN2-25134H) for concrete and 1/4" x 2 3/4" Titen 2 screws (model TTN2-25234H) for GFCMU. Follow all installation instructions and use the table loads from the sawn lumber or EWP tables.
Attach the hangers to concrete or GFCMU walls using hex-head Titen 2 screws. Titen screws for GFCMU (1/4" x 2 3/4" — model TTN2-25234H) and for concrete (1/4" x 1 3/4" — model TTN2-25134H) are not provided with the hangers.
Drill the 3/16"-diameter hole to the specified embedment depth plus 1/2".
Alternatively, drill the 3/16"-diameter hole to the specified embedment depth and blow it clean using compressed air.
Caution: Oversized-diameter holes in the base material will reduce or eliminate the mechanical interlock of the threads with the base material and will reduce the anchor’s load capacity.
Titen Installation Tool Kits are available. They include a 3/16" drill bit and hex-head driver bit (model TTNT01-RC); a 3/16" x 4 1/2" drill bit is also available (model MDB18412).
A minimum edge distance of 1 1/2" and minimum end distance of 3 7/8" is required. See installation image "HUC410 Installed on Masonry Block End Wall" in image gallery.
Where no uplift load is required, a minimum end distance of 1 1/2" is permitted.
