Seamless mounting: the two wall-mounting Z-clips fit together perfectly to form a solid and sleek support. Since the photo hook is only 2mm thick per piece, there is only a very small gap against the wall. Superior Security: Recessed mounting brackets with Z-clips provide secure hold to prevent mounted objects from falling. Premium cold-rolled steel with high corrosion resistance ensures durability for long-term use. Easy Installation: Sleek design with countersunk and symmetrical screw holes allows for quick and simple installation. Attach one clip to the wall using long screws with reinforcement facing up, then attach the other clip to the furniture using short screws with reinforcement facing down, and snap them together. Wide Applications: The interlocking hooks are ideal for securing photo frames, artworks, display paintings, posters, headboards, clocks, mirrors, and more, adding a clean and elegant look to your home or office. Convenient and reusable: The sturdy flush mounting brackets can be used individually for lightweight items such as small pendant lights. For heavier wall hangings, use multiple hangers for best results. To remove wall-mounted items for cleaning or repositioning, simply lift the item up from the brackets. Note: Measurements are manually taken; please allow a tolerance of 13 cm. Due to lighting and display differences, slight color variations may occur.
