Special care should be given to ensure proper installation of spring clips on your connecting links. It is important that the spring clips are assembled snug in the retaining ring grooves on the connecting links. Secondly, there are two styles of spring clip connecting links – open end and closed end (Q-type) style connecting links. In both cases the opening of the spring clip should ALWAYS face opposite the direction of travel of the chain strand. If problems persist, contact us for further assistance.
