CLGR® DIN 5683 Long Link Chain, also named DIN5683 round link chain.
DIN 5683 Long Link Chain is a welded steel chain engineered for general-purpose applications across engineering, industrial, agricultural, and marine sectors when paired with compatible accessories.
As products engineered by leading link chain manufacturers, the chain links for sale are manufactured to international standards and features elongated links that provide flexibility and durability in dynamic environments.
CLGR® DIN 5683 Long Link Chain is particularly well-suited for farming equipment and marine mooring applications, where its robust construction and corrosion-resistant finishes (e.g., hot-dip galvanized or electro-galvanized options) ensure reliable performance under demanding conditions.
