2A
Beveled plate for slopes greater than ¼ :12.
Code-recognized connectors may be
substituted. For slopes greater than 4:12
connectors are required to resist lateral thrust.
Minimum attachment:
For slope ≤ ¼:12, one
10d box nail at each side of
bearing. For slope> ¼ :12
design joist attachment
to beveled plate to
transfer lateral
thrust.
Attached beveled plate
to framing with
one - 16d at 16" o.c.
2B
For roof slopes between ¼ :12 and 12:12,
provide a strap wrapped around
ridge beam
Ridge beam
(Glulam or
LVL)
Adjustable Slope
Hanger with a
minimum unadjusted
uplift capacity of 300 pounds
unfactored resistance.

Bearing stiffeners required
when hanger does NOT
support I-Joist top flange
Application limited
to 4:12 pitch or less
Backer block: If top mounted
hanger is fully supported by top
flange, backer block only required on hanger side. If face nailing
is required, then install a backer block on the back side. Install
a backer block and filler block if a multiple I-joist is required. Nail
with ten -10d nails for flanges up to 1¼" wide. Use twelve-10d nails
for flanges wider than 1¼".

All nails shown in the details below are assumed to be common nails unless otherwise noted. 10d box nails may be substituted for 8d common shown in details.
Individual components not shown to scale for clarity.
Bearing stiffener required
when end reaction exceeds
the "no stiffeners" factored
reaction resistances indicated
in this guide.
8d nails @ 6" o.c.- minimum
three-8d nails per blocking panel
(when used for lateral shear
transfer, match nail type and
sheathing edge nailing "boundary
nailing" for engineered
diaphragm applications)
Use minimum 8d nails.
