Connecting link (CLS pf) with clip; shouldered pin; press fit. - Optional ''clip-style'' master link for 530 RQ2 series chains - Gold colored link plates. Note: See 993734 for standard pin link (rivet style) master link. Note: Clip style connecting links are master links than can be disconnected again. The pin links are master links that are riveted to obtain the safest possible option to connect the chain. Tsubaki supplies; and strongly suggests; the use of pin links in combination with O-ring chains for safety reasons. Connecting links for O-ring chains must be purchased separately when desired.Note: A clip-style connecting link has just 85% of the strength of a riveted-style pin link. Tsubaki advises to use riveted style pin links in all applications and will not be liable for connecting link style applications.
