Grip Anchor

This anchor will work with a bolt or threaded rod in any length.
Drill holes same length as anchor for flush finish or deeper for more embedment into concrete.
Place the special setting tool on the top of anchor then strike until the anchor flushes with concrete and the strong hitting reflection is perceived.
If anchor is no longer needed, can fill with cement to make the surface smooth again.
The anchor is set (fully expanded) when the shoulder of the setting tool seats on the top of anchor.
