Dottie's concrete anchors are faster to install than most steel anchors, yet have significant load capacities. One tool drills the hole and sets the anchor without the need to remove from the drill chuck. They have the added advantage of close-to-edge fastening without potential breakout. These anchors work in poured concrete, prestressed concrete, cinder block and brick and mortar and can be loosened for adjustment or removed. CAUTION: Always wear eye protection!
