It is important that you drill your Miller Grip anchor hole to the manufacturer's required depth and hole
structure. All holes must be 3/4" in diameter and drilled at least 3" deep into the concrete substrate.
The bored hole walls must be straight and parallel. The bored hole must be of uniform diameter and
free of peaks and valleys on the inner wall surfaces. Use only quality industrial grade rotary hammer
drills and rotary hammer drill bits. NEVER USE A BENT DRILL BIT! DO NOT USE masonry drill bits.
Drill a straight 3/4" diameter hole at least 3" deep into concrete substrate
with a rotary hammer drill that uses industrial grade SDS bits.
When placing a Miller Grip anchor, place your thumb inside the anchor loop and your first two fingers
around the trigger. Retract the trigger until the spring bottoms out. With your hand, pinch the two spoons
between your thumb and index finger. Hold the trigger fully retracted while inserting the unit into the bot-
tom of the hole.

If a Miller Grip anchor becomes stuck, insert a

plate will be easily visible at the edge of the hole.
