Laclede 1/2" (13mm) Square "Lockdown" Security Chain

Laclede Lockdown™ Square-Link Security Chain | Sold by the Foot

Laclede Lockdown™ Security Chain is a premium hardened square-link chain engineered for serious theft prevention. Manufactured from quenched and tempered alloy steel and through hardened (62–65 HRC), this chain delivers superior resistance to cutting, grinding, and prying compared to traditional case-hardened security chain.

The square-link design limits effective attack angles for bolt cutters and saws, making it significantly more difficult for thieves to gain leverage. Designed for protecting trailers, heavy equipment, gates, jobsite tools, motorcycles, ATVs, and industrial assets, Lockdown™ chain is built for high-risk environments where security matters.

Sold by the foot for fully customizable lengths to fit your specific application.
