12B-4 offset links are also called 12B-4 half links; an offset link is designed uniquely to adjust the length of a chain by half a pitch. 12B-4 offset links come in handy when removing or adding a small length in the chain or repairing an existing chain. The DUROCHAIN 12B-4 offset link is constructed from the best quality raw carbon steel materials; each component undergoes a set of particular processes to improve strength, fatigue resistance, and performance. We also equipped this link with a solid bushing, roller, and hardened pin! Finally, we produced a genuine tier one 12B-4 offset link to pair perfectly with our premium quadruplicate 12B-4 roller chain!
