Top-Flange Hangers – Load Tables for I-Joists/SCL, 3 1/2 x 18 – 3 1/2 x 30

Joist Hanger Tables
  1. Loads may not be increased for duration of load.
  2. Uplift loads are based on DF/SP lumber and have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern. For SPF/HF use 0.86 x DF/SP uplift load.
  3. When I-joist is used as header, all nails must be 10d x 1 1/2" and allowable loads assume flanges that are at least 1 1/2" thick made of Douglas Fir, LVL or LSL. For other flange thicknesses, apply load adjustment factors found in the table below.
  4. Hangers sorted in order of recommended selection for best overall performance and installation value.
  5. Other nail schedules and loads are listed on individual hanger pages: ITS/MIT/HIT, LBV/BA/B/HB, W/WP/WPU/WM/WMU/HW/HWI/HWU, EQQ.
  6. See here for Code Reports.
  7. Web stiffeners are required where noted, when sloped or skewed, and when supporting double I-joists with flanges less than 1 5⁄16" thick in hangers that are 14 gauge and thinner.
  8. For 2 1/4"x22" and 24" joist sizes, refer to technical bulletin T-BSERIES.
  9. Nails: 16d = 0.162" dia. x 3 1⁄2" long, 10d = 0.148" dia. x 3" long, 10d x 1 1⁄2" = 0.148" dia. x 1 1⁄2" long. See other nail sizes and information.
