Description
MARQUIP® forged detachable chain connecting links replace bulky shackles and end links. They make better-than-original repair or replacement links, they serve as connecting links for 90′ shots of chain, and they ride through hawse pipes and over wildcats as smoothly as normal chain. Made of alloy steel, heat-treated to a tensile strength of approximately 150,000 PSI, they’re as strong as or stronger than the chain.
The positive-lock assembly consists of a stainless steel pin and lead plug; the pin can be removed with a sledge and drift for disassembly. Proof and break tests surpass USN and ABS requirements. Links are available in sizes up to 3-1/2″. Links are available in sizes up to 4-3/4″.
