Step-by-Step Instructions
1) Locate the rafter underneath
the decking of the roof by locating
the screws. The rafter lies directly
underneath the screws.
2) Drill a pilot hole through the roofing
material into the rafter to ensure that
the lag bolt will be located into a solid
portion of the rafter. If the rafter is
not found then seal the pilot hole
immediately with roofing sealant.
3) Apply roofing sealant if needed
directly onto the pilot hole and
lag to ensure a water tight seal.
4) Attach the Corrugated Block with
L-foot using a 5/16” lag bolt (TYP)
or appropriate lag with a minimum
embedment of 2 ½” lag shank into
the rafter. Tighten lag bolt to seat.
5) Tighten L-foot assembly silver
hardware to 10–16 ft-lbs and tighten
black hardware to 8-10 ft-lbs.
