Heavy-duty cavity wall anchors designed to deliver a secure, stable fixing in hollow substrates such as removable plasterboard, plywood, particleboard and fibreboard. Key benefits Strong, reliable hold: Made of heavy-duty materials for extra grip and screw tensioning so fixtures stay secure under load. Versatile installation: Can be set with a spring-loaded setting tool or simply by tightening and removing the screw, so you can choose the quickest method for the job. Anti-rotation and high load capacity: Two anti-rotation teeth prevent turning during installation and reinforced anchor wings spread load across the cavity for a stable fixing. Flexible screw compatibility: Combination screw heads accept both slotted and driven screwdrivers, giving you compatibility with common tools. Main features Purpose: Anchors for most cavity wall situations, optimized for hollow boards and lightweight panels. Fixing action: Expanding wings engage behind the panel to create a secure clamp against the back of the board. Anti-rotation: 2 anti-rotation teeth to hold the anchor steady while you drive the screw. Screw head compatibility: Combination head accepts slot and drive bits for flexible installation. Setting options: Use a spring-loaded setting tool or tighten and remove the screw to set the anchor in place. Sizes and grip ranges Choose the size that matches your panel thickness: from x 20mm for 0mm–5mm grip wall thickness to x 46mm for 16mm–24mm grip wall thickness. Multiple sizes are available to match different wall thicknesses. Typical applications Hanging shelving, mirrors or coat racks on plasterboard where a secure, concealed fixing is needed. Fixing lightweight cabinets, speaker brackets or fittings to hollow plywood or particleboard panels. Installing fixtures in temporary or removable partitions where a non-permanent, high-strength anchor is required. Practical notes Confirm panel grip thickness before selecting anchor size to ensure correct expansion and load performance. For best results in heavy or safety-critical applications, use the spring-loaded setting tool where available. The anchors are intended for use in hollow substrates; do not use in solid masonry without appropriate anchors. These anchors provide a straightforward, dependable solution for fastenings in cavity and hollow wall materials, combining easy installation with anti-rotation features and reinforced wings for improved load distribution.
