Drop-in anchors are specifically designed for use with concrete. The anchor consists of two components: the anchor body and the expander plug. When the drop-in anchor is installed in a concrete product or structure, the plug forces the anchor to expand inside the hole. Friction holds the anchor permanently in place. The strength of the drop-in anchor depends on several factors including its size, the depth of the hole that drilled to accommodate the anchor and the strength of the concrete.
Examples of the numerous drop-in-anchor applications include the installation of handrails, shelves, overhead hangers, machinery and lighting fixtures.
