This is Laclede's take on a security chain, which they call "Lockdown Chain". It sells extremely well, in part because people trust the Laclede brand. They are a domestic manufacturer of many types of chain, including high-quality overhead lifting chain, tie down chains and tire traction chains. Their Lockdown Chain is thru-hardened to 45-48 HRC, meaning it's just as hard to cut in the middle as it is on the outside. This makes the process slow and tedious for a would-be thief. Some of the most popular security chain on the market is only case-hardened--while the design is different, both work well. Now available in two sizes, 3/8" (10mm) and 1/2" (13mm). For many, 3/8" is considered the perfect size--beefy, but not too heavy or cumbersome. But other customers like the 1/2" size, which is the biggest security chain we offer in any brand!
Both are made from quenched and tempered alloy steel with an electro-galvanized finish. It's worth noting that Laclede is the primary chain manufacturer we use for building Grade 100 chain slings because we trust their quality so much. This chain is available by the foot, in full drums, or in kits paired with Laclede's super tough padlock (kits are discounted 10%).
