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.
Galvanized; ZMAX® and stainless steel available
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.
