Recommended Anchor Attachment Points
Roof structures that are designed and fabricated
according to the IBC do not contain discriminatory
attachment points for anchors. The structure is a
network or grid of interconnected members and,
as a system, is designed to transfer and share loads
between those members as loads are applied to
the roof. Three-truss anchors require the temporary
addition of wooden 2x4s for bracing in accordance
with SBCS mandates, using a process that
is well documented and understood by builders.
Nailed anchors are intended to be placed on top of
sheathing and centered on a truss—an easily followed
procedure. As long as the installer follows
the anchor manufacturer’s instructions, the anchor
will perform as intended. This method was followed
for all but one of the anchors that held the
worker in the arrested falls.
