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°. Most models have triangle and round holes. To achieve maximum loads, fill both round and triangle holes with common nails. These heavy-duty connectors are designed for additional strength, longevity and safety factors.
"Use all specified fasteners; see General Notes
Joists sloped up to 1/4:12 achieve table loads
When nailing into solid sawn carrying member's end grain, the allowable load is adjusted by a factor of 0.69"
