The most secure fitting available to attach items to the artiteq hanging system. The frame ratchet mechanical design is based on the trusted and widely used 9.4261 Ratchet Hook. Once attached simply bottom feed the steel wire through the frame ratchet and the spring mechanism locks the steel wire into place. With this hook you can take comfort that the frame will not come off the wall even in an earthquake. The other feature is that theft of your artwork becomes a little more difficult.
