Description
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.
Material
- See tables
Finish
- Galvanized. Some products available in ZMAX® coating.
Installation
- 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.
Options
- For both flanges concealed, order HUC.
- When the HUC is skewed, the header flange opposite the skew direction is not concealed. See image gallery.
- The HU with widths equal to or greater than 3 9/16" is available with the A flanges straight at table loads listed.
- For low-cost, code approved 45° skewed hangers, see SUR/SUL.
- For field-adjustable hangers, see LSSJ, LRUZ and LSSR.
- 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).
- LU/LUC cannot be modified.
Product Notes
- Model configurations may differ from those shown. Some HU models do not have triangle holes. Contact Simpson Strong-Tie.

U/HU/HUC Series Modifications and Associated Load Reduction Factors
- Modified seat is sloped, skewed, or both. If sloped only or skewed only, use a smooth-shank stainless-steel reduction of 0.65.
- 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.
- Skews over 50° require a square-cut joist.
