Instructions
1. Use the correct size masonry drill bit (one included in
every box) and drill the hole at least
1/4" deeper than the calculated embedment depth.
It is recommended that a minimum of 1" and a
maximum of 1-3/4" embedment be used.
2. Clean the hoe using a nylon brush and
compressed air.
3. Place the anchor point through the xture into hole.
4. Drive the anchor in a single continues motion until
the anchor is set rmly against the xture.
NOTE: Always wear safety glasses. Normal safety precautions should be
observed when drilling the holes to avoid electrical installations, other utilities
and reinforcement bars.
