People simply 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. You can literally find their chains in use all over this great country--construction sites, passenger cars, marine applications, you name it, Laclede is there. They are adaptive too, willing to make changes with their engineering to keep up with modern demands. For example, their Lockdown Security Chain used to be thru-hardened with a lower HRC rating. Laclede's design team determined their chain would be even tougher to cut being case-hardened yet with a much higher HRC rating (62-65 HRC). They brought this change to market quickly, and now have a security chain that stacks up against ANY competitor.

What Sizes Are Available?
Lockdown chain is available in three sizes: 9/32 (7mm), 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! And for lightweight bicycle use, the smaller 9/32" size might be your best bet. All sizes are made from quenched and tempered alloy steel with an electro-galvanized finish. Available by the foot, in full drums, or in kits paired with Laclede's super tough padlock (for use with 3/8" and 1/2" chain only, kits are discounted 10%).
