Steel / expanding drop-in anchors are used for fastening components in
concrete walls and floors. They are most often combined with other ventilation
elements, including SR2G stud bolts and PG threaded rods.
The recommended tool for installing drop-in anchors is TK-DOB driver,
which drives the anchor's core inward, spreads the expanding arms, and
fits the drop-in anchor tightly into the concrete.
