The HUC is designed for structures requiring additional strength and safety factors. These face-mount joist hangers have concealed header flanges providing cleaner visible lines in exposed conditions. Some models of this heavy-duty hanger can be special ordered with a skewable seat and a seat that slopes as far as up to 45°.

Key Features

  • Extra optional triangle holes for additional load
  • HUC-series hangers are tested, load rated and code compliant


  • 14 ga. (68 mil)


  • Galvanized


  • Use all specified fasteners; see General Notes.
  • Can be installed filling round holes only, or filling round and triangle holes for maximum values.
  • Joists sloped up to 1/4:12 achieve table loads.
  • For installations to masonry or concrete, see HUC in Masonry Hangers.
  • Can be welded to a steel member. Allowable loads are the lesser of the values in the hanger tables or the weld capacity — refer to technical bulletin HU/HUC Welded onto Steel Members (T-C-HUHUC-W).
  • When nailing into solid sawn carrying member's end grain, the allowable load is adjusted by a factor of 0.67.

HU/HUC Series Modifications and Associated Load Reduction Factors

HU/HUC Series Modifications and Associated Load Reduction Factors
  1. Modified seat is sloped, skewed, or both. For stainless-steel hangers, if sloped only or skewed only, use a smooth-shank stainless-steel reduction of 0.65.
  2. For hanger applications with both flanges concealed, W must be at least 2 5/16". To order, ask for HUCXXX. For skewed HUC, only flange on acute side is concealed.
  3. Skews over 50° require a square-cut joist.
