What Kind Of Chain Is This?
This is a true security chain, made from square, case-hardened links to resist cutting. Laclede recently changed their heat treating process to make this chain 62-65 HRC. Made from quenched and tempered alloy steel with an electro-galvanized finish for corrosion protection. Laclede calls it "Lockdown Chain" for a good reason, and at 3/8" (10mm) in diameter, this chain is considered by many to be the ideal size.
