John King Climax premium combination chains are most commonly used in light-to-medium duty conveying applications where a durable yet cost effective chain is needed. Combination chains are often utilized for stone, gravel, coal and other abrasive materials. They are manufactured with hardened cast block links and heat-treated steel sidebars and pins to withstand the abuse of industrial applications. Our combination chains are designed and fully tested for dimensional consistency, interchangeability, and correct sprocket engagement. Most standard sizes are available from stock, with MTO and custom designed chain and attachments also available.
