The anchors are easily installed by hitting a hammer on the head that drives the pin through the anchor, expanding the body of the anchor to hold it in place. Ideal for use in concrete, CMU, brick, and other base materials. Pin and head configuration is designed to make anchor tamper-resistant. This product is not for use in overhead applications.
