LUC/LU/U/HU/HUC Standard Joist Hangers
LUCZ concealed-flange hanger available for 2x6, 2x8, 2x10 and 2x12 lumber. Ideal for end of ledger/header or post conditions, the LUCZ also provides cleaner lines for exposed conditions such as overhead decks.
See hanger tables. See Hanger Options for hanger modifications, which may result in reduced loads.
LU — Value engineered for strength and economy. Precision-formed — engineered for installation ease and design value.
U — The standard U hanger provides flexibility of joist to header installation. Versatile fastener selection with tested allowable loads.
HU/HUC — 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 schools and other structures requiring additional strength, longevity and safety factors.
- See tables
- Galvanized. Some products available in stainless steel or ZMAX® coating. See Corrosion Information.
- Use all specified fasteners. See General Notes.
- HU/HUC — 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 HU/HUC/HSUR/L.
- HU/HUC 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-HUHUC-W).
- When nailing into carrying member's end grain, the allowable load is adjusted by a factor of 0.67.
- For both flanges concealed, order HUC.
- The HU is available with the A flanges straight. Standard reductions apply for alternate fasteners.
- For low-cost, code approved 45° skewed hangers, see SUR/SUL.
- For field-adjustable hangers, see LSSJ, LSU, LRUZ and LSSU.
- See table-modifications table for available options and associated load capacities for U and HU hangers.
- For ease of ordering, refer to technical bulletin U/HU Hanger Special Order Worksheet (T-U-HU-WS).
- Model configurations may differ from those shown. Some HU models do not have triangle holes. Contact Simpson Strong-Tie.
