Double expansion anchors are two-piece tubular shields designed for secure fastening in masonry, concrete, brick and block. These zinc-plated anchors feature a hollow wedge cone and wedge nut system that expands at both ends when tightened, providing firm, reliable holding power.

These anchors work with mechanical screws or bolts and are suitable for both soft and harder masonry materials. The two-piece design ensures even expansion for consistent grip strength across your installation.
