SEAMLESS ASSEMBLY: The two interlocking clips fit together perfectly to form a strong, interlocking assembly. Since the photo mount is only 1.5mm thick per piece, there is very little space against the wall. SUPERIOR SECURITY: Flush mounting brackets provide ultimate security to prevent mounted objects from falling. Premium cold-rolled steel with maximum corrosion resistance gives the wall mount clamps durability for extended use. EASY INSTALLATION: Sleek design with countersunk, symmetrical screw holes allows for quick and easy installation. Simply attach one clip to the wall with long screws with the bulge facing up, then attach another clip to the furniture with short screws with the bulge facing down, finally locking them. WIDE APPLICATIONS: The interlocking hangers are perfect for attaching picture frames, artwork, exhibition paintings, posters, headboards, clocks, mirrors and more, bringing elegance to your home and office. PRACTICAL AND REUSABLE: The heavy duty flush mount brackets can be used individually for small hangings. For large wall hangings, multiple mounts are recommended. When you need to remove the objects fixed to the wall for cleaning or other reasons, just lift them off the brackets.
