Hollow Wall Cavity Anchors are specialized fasteners designed for secure fixing into drywall, plasterboard, and other hollow substrates. They work by expanding behind the wall surface to form strong load-bearing wings that prevent pull-out. Manufactured to ASTM and DIN standards, they are available in steel, stainless steel, and zinc alloy variants. These anchors provide a reliable fastening solution for medium-duty loads where standard plugs are insufficient. They are widely used for shelving, curtain rails, electrical fittings, cabinets, and interior installations.
