Premium cold rolled steel with maximum corrosion resistance gives the wall mount clamps durability for extended use.<br> EASY INSTALLATION: The sleek design with countersunk and symmetrical screw holes allows for quick and easy installation. Just fix one clip on the wall using long screws with the bulge facing up, then fix another clip on the furniture using short screws with the bulge facing down, finally lock them.<br> GREAT APPLICATIONS: Interlocking hangers are perfect for attaching picture frames, artwork, display paintings, posters, headboards, clocks, mirrors and more, bringing elegance to your home and office .PRACTICAL AND REUSABLE: Heavy duty flush mounting brackets can be used individually for small pendant lights.
