Installation Guidelines
Using the proper diameter bit, drill a hole into
the base material to a depth of at least 1/4"
deeper than the required embedment. The
tolerances of the drill bit used should meet the
requirements of ANSI Standard B212.15. Blow
the hole clean of dust and other material.
Insert the anchor through the fixture and
into the drilled hole. Drive the nail into the
anchor body to expand it. Be sure the head
is seated firmly against the fixture and that
the anchor is at the proper embedment. Take
care not to overdrive the nail. This anchor
is not recommended for installations at an
angle or use overhead.
