Double Roller Chain

Double strand roller chain is also commonly referred to as a duplex roller chain and consists of two single strands of roller chain that is manufactured together. The benefit of a double roller chain is a high-strength chain with a relatively small form factor, the purpose of a chain is to transmit energy to the highest possible degree of efficiency. You'll find that our roller chains not only have a high transmission of energy but are of superior quality and strength compared to other chains on the market. We stock standard carbon steel, stainless steel, nickel-plated, coated, and specialty double roller chains. We also stock sprockets, chain tools, and wear guides for duplex chains as well.
