Selected Materials: The hanging buckle and screws are made of high-strength stainless steel, both of which have anti-rust, anti-corrosion and indoor and outdoor durability, making the wall-mounted picture hanging clip durable and long-term use. Interlocking Design: Two interlocking Z-shaped clamps are perfectly matched to form a sturdy, streamlined interlocking bracket. Since each photo frame hanger is only 2 mm/0.08 inch thick, there is only a small gap against the wall. Convenient Quick: Align the expansion tube with the screw hole and put it in, then screw in the screw, then fix one clip protruding part up to the wall, then fix the other clip protrusion down to the furniture, and finally interlock the installation . After installation, items can be taken off the wall or hung on the wall at any time. Wide Range of Applications: The embedded concealed bracket is very suitable for fixing photo frames, posters, art paintings, makeup mirrors, headboards, modular furniture, etc., so that the furniture can be installed firmly and bring a lot of convenience to your life.
