Inner links within a chain are sometimes too small to connect other components to the chain, so the 10mm Grade 80 Hammerlock is the best solution for that issue. This link is designed to allow you to easily connect other, even multiple, end fittings, hooks, links, and other components to increase the versatility and length of your tie-down chain assembly. Built from high-quality steel, assembling and disassembling the link takes no time or effort, allowing you to easily attach it to the chain with no trouble. The 10mm Grade 80 Hammerlock is made to comply with ASNZ 4344 2001
