General Notes for Hanger Options

Technical & Installation Notes

Hanger Options

The Hanger Options Matrix for Face-Mount and Top-Flange Hangers in each of the respective hanger sections shows hanger modifications and special applications (uplift, nailers and weldability) that are available for each model series. Modifications may not be available for all models in the series, and some combinations of hanger options are not available. Many hanger modifications result in load reductions. For all modifications, refer to the listed hanger option pages for additional information regarding the availability of each modification, associated load reductions, and installation requirements. For joists sloped up to 1/4:12, there is no load reduction. For slopes greater than 1/4:12, see individual product pages or refer to technical bulletin T-C-SLOPEJST at strongtie.com. For more information regarding the applications, refer to the individual product pages throughout the catalog.

For attaching to headers made up of multiple plies, refer to T-C-MPLYHEADR.

Hanger Option General Notes

This information applies only to the hangers manufactured by Simpson Strong-Tie and installed per our instructions. Some combinations of these options on a single hanger have not been evaluated. In some cases, combinations of these options cannot be manufactured. A qualified designer must always evaluate each connection, including header and joist limitations, before specifying the product.

Testing is performed using a standardized hanger test method. The joist in the test setup may include the minimum amount of structural stability where appropriate. For example, the sloped down hanger tests are assembled with a joist cut on the lower end to lie flush with a wood member attached with three 8d common toenails. Header and other attached structural members are assumed fixed in actual installations. Horizontal loads induced by sloped joists must be resisted by other members in the structural system.


Gauge may vary from that specified depending on the manufacturing process used. U, HU, HUTF, WP and BA hangers normally have single-piece stirrups; occasionally, the seat may be welded. Hanger configurations, height and fastener schedules may vary from the tables depending on the joist size, skew and slope.


See specific hanger tables. Welded specials: Simpson Strong-Tie gray paint. Specials that are not galvanized before fabrication can be hot-dip galvanized after fabrication; specify HDG.


Modified hangers, due to their numerous variations, are not on code reports.


For multiple modifications on the same connector, use the single multiplier factor that yields the lowest design loads.

To Order

Use the abbreviations below to order specials. The example shows a HWP3.56X hanger and illustrates most available options; most special hangers have only a few of these features. For assistance, contact Simpson Strong-Tie.


  • Fastener quantities may be increased beyond the amount specified in the standard hanger table.
  • Fill all holes with the table-specified fastener types.
  • Some skewed hangers require bevel cut joists; refer to the specific notes provided for each product.

For assistance, contact Simpson Strong-Tie.

The Joist Hanger Selector software enables you to select the optimal product for your project. The software takes into consideration all the characteristics seen on this website.

Height for Sloped Hangers

Height 1 (H1) is the joist height before the slope cut has been made.

Net Height (Net H) is the joist height after the slope cut has been made.

Provide H1 when ordering a connector. Connectors are made assuming dry lumber is being used in continuously dry conditions.

Simpson Strong-Tie will calculate the Net H dimension based on the mathematical formula of H1/cos angle.
