This 30-piece set of galvanized steel impaling clips delivers a heavy-duty, reliable mounting solution for acoustic panels in recording studios, home theaters, offices, and beyond—perfect for both professional installers and DIY sound treatment projects. Crafted from robust galvanized steel with hardened steel prongs, these clips resist rust, corrosion, and bending, ensuring long-lasting performance even under the weight of dense acoustic panels. Designed for repeated use across diverse environments, they offer exceptional durability without compromising on ease of installation. Thanks to the intuitive push-on design, mounting is fast and simple: simply align the clip with the panel edge and press down—the sharp, angled prongs pierce the panel backing and lock it securely to the wall substrate for a clean, flush finish. Compatible with drywall, plywood, and masonry surfaces, these clips work seamlessly with most fabric-wrapped or rigid acoustic panels. The hidden-mount system preserves a sleek, professional appearance while maintaining the critical air gap behind the panel to boost low-frequency absorption. Each clip measures approximately 4" x 3", and the 30-piece quantity supports medium to large-scale acoustic treatments. Please note: Screws and wall anchors are not included. You'll need to supply appropriate fasteners based on your wall type (e.g., drywall anchors, masonry screws, or wood screws).
