KingChain Passing Link chain is an excellent general purpose, low carbon utility chain. The wide link design allows the links to easily pass 1 another, reducing the chance of binding or kinking. The chain is manufactured to NACM standards. Each link is proof tested 2 times and the break load is 4 times the Safe Workload (design factor 4:1). Passing Link is recommended for applications that do not require high strength-to-weight ratios. It is often used on farms with livestock and at home for general purpose applications. Chain is zinc plated for a bright, attractive finish with moderate corrosion resistance. Do not use for overhead lifting. Never exceed the Safe Working Load (SWL).
