Product Details
The HB is a top-flange hanger designed to carry medium to high loads for solid sawn and engineered wood applications. This heavy beam hanger features a full-height joist flange that captures the top chord of the joist to prevent rotation. With its one-piece design, the HB provides a cost-effective solution compared to welded hangers.
Key Features
- Efficient design that provides a cost-effective options for high-load applications
- Available for special order to accommodate sloped and/or skewed members
Material
- 10 gauge
Finish
- Galvanized. May be ordered hot-dip galvanized; specify HDG.
Installation
- Use all specified fasteners; see General Notes and nailer table.
- May be used for weld-on applications. The minimum size weld is a 2"-long fillet weld to each side of each top flange; weld size to match hanger material thickness. Distribute the weld equally on both top flanges. Welding eliminates the top and face nailing requirements. Consult the code for special considerations when welding galvanized steel. The area should be well-ventilated; see General Instructions for the Installer, note k for weld information. Weld-on applications produce the maximum allowable download listed. For uplift loads refer to technical bulletin Top-Flange Hanger Reductions for Multiple-Ply Headers (T-C-WELDUPLFT).
- Web stiffeners are required for I-joists.
- Ledgers must be evaluated for each application separately. Check TF dimension, nail length and nail location on ledger.
- Refer to technical bulletin Sloped Joist in Non-Sloped Hangers (T-C-SLOPEJST) for information regarding load reductions on selected hangers which can be used without modification to support joists which have shallow slopes (≤ 3/4:12).
- Bevel-cut the carried member for skewed applications.
Options
- Other widths are available; specify W dimension (the minimum W dimension is 1 9/16").
- For modified hangers, fastener quantity listed in tables may need to increase depending on joist size, skew and slope.
- Hangers may be modified for slopes and/or skews up to 45º. The top flanges may be sloped as much as 35º and may be open or closed up to 30º. See Modifications and Associated Load Reductions below.

Load Tables
See Hanger Options for hanger modifications, which may result in reduced loads.
Nailer Table
The table indicates the maximum allowable loads for BA and HB hangers used on wood nailers. Nailers are wood members attached to the top of a steel I-beam, concrete or masonry wall.
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern. Refer to technical bulletin T-C-NAILUPLFT for additional information.
- Steel nailer allowable loads apply to steel header material with thickness between 1/4" and 3/4" with minimum Fy = 36 ksi. Design of steel header by Designer.
Various Header Applications
- This table assumes joists with Fc ⊥ = 750 psi. For other joists, check that bearing and joist nails are adequate.
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
- Uplift loads are based on DF/SP lumber. For SPF/HF, use 0.86 x DF/SP uplift load.
- Loads may not be increased for duration of load.
- SCL (structural composite lumber) is LVL (laminated veneer lumber), LSL (laminated strand lumber), and Parallam® PSL.
- LVL headers are assumed to be made primarily from Douglas fir or southern pine. For LVL made from spruce-pine-fir or similar less-dense veneers, use the values found in the SPF/HF column.
- DF I-joists headers include flanges made from solid sawn Douglas fir, LVL made primarily of DF/SP, or LSL. For I-joist header flanges with thicknesses from 1 5/16" to 1 3/8", use 0.85 of the I-joist header load. For I-joist header flanges with thicknesses from 1 1/8" to 1 1/4", use 0.75 of the I-joist header load.
Modifications and Associated Load Reductions1
- Reduction factors are not cumulative. Use the lowest factors that apply.
- Web stiffeners are required for sloped or skewed conditions.
- For straight-line interpolation, "a" is the specified angle.
