Proven Locks carries the most complete lineup of American-made trailer security products available in one place — from coupler locks and puck locks to hitches, hasps, and job site security. Every product is engineered for a custom-molded fit, not an approximate one, which means no rattling, no slipping, and no guessing whether your lock will actually hold. Whether you're securing a landscaping trailer, a boat, or a job site box, you'll find the exact lock rated for your setup here.

Trailer theft happens in minutes — a poorly fitted lock invites it. Every Proven Locks product eliminates the weak points that bolt-cutter thieves and ring-and-chain tactics exploit: loose fit, exposed shackles, and drill-vulnerable cylinders.

• American-made construction across the full product line
• Custom-molded fit for a tight, rattle-free connection on every lock type
• Tamper-proof lock cores — Cobra standard, disc-detainer and Medeco upgrade options
• Full range: coupler, gooseneck, puck, wheel, hasp, specialty, and hitch products
• Free same-day shipping on orders placed before 2 PM EST
