Backer block (use if factored hanger load exceeds 360 lbs.) Before installing a
backer block to a double I-joist, drive three additional 3 inch nails through the
webs and filler block where the backer block will fit. Clinch. Install backer
tight to top flange. Use twelve 3 inch nails, clinched when possible. Verify
hanger capacity with manufacturer. Maximum factored resistance for
hanger for this detail = 1620 pounds.
Backer blocks (Blocks must be long enough to permit required nailing without splitting)
Material Thickness Required* Minimum Depth**
* Minimum grade for backer block material shall be Utility grade SPF (south) or better
for solid sawn lumber and Rated Sheathing grade for wood structural panels.
**For face-mount hangers use net joist depth minus 3¼".
Top - or face - mounted hanger Double I-Joist header
Note: Unless hanger sides laterally
support the top flange, bearing
stiffeners shall be used. Backer blocks
are not required for top mount hangers
with factored reactions less than
360 pounds.
Face-mount hangers shallower
than the joist depth shall
have full depth bearing
web stiffenners and
shall have
side flanges
at least 60%
of the joist
depth.
Backer block required
