83020 DEA14 1/4 DOUBLE EXPANS

Double Expansion Anchors are designed for anchoring into concrete, brick, or block base material. Inserting a machine-threaded bolt into the anchor expands it against the concrete at two points. These anchors are made from Zamac, a non-rusting material. They are intended to be set flush with the base material and are considered a light to medium-duty fastener.
