Proven Industries Trailer Locks

Real Security for Louisville & Southern Indiana

A cheap lock is a suggestion. A Proven Industries lock is a stop sign. Built in the USA with coupler-specific housings and hardened hardware, these locks fit like a glove and shut down quick-hit thefts at job sites, driveways, and storage lots. Pair your lock with the right trailer from our dump, gooseneck, and enclosed pages for a setup that protects your investment end-to-end.

Why Proven Industries?

  • Coupler-specific fit: Model-matched housings are harder to pry, shim, or twist off than generic “one-size” locks.
  • Made in the USA: Purpose-built materials and tight tolerances for real-world abuse.
  • Keyed-alike options: Run one key across your fleet — fewer key rings, faster mornings.
  • Coverage for more than couplers: Gooseneck, wheel, and door/puck solutions for 360° protection.

How to Pick the Right Lock

Snap two photos of your coupler (top and side), or bring the trailer by. We’ll match the exact model — no guesswork. Typical fits:

  • 2" ball couplers: Common on light utility and some enclosed trailers.
  • 2-5/16" ball couplers: Most heavy utility, dump, equipment, and cargo trailers.
  • Gooseneck couplers: We’ll confirm brand/style and set you up with a lock that actually covers it.

Pro Tips to Deter Theft

  • Use two layers: a coupler lock and a wheel or puck/hasp lock for doors.
  • Park nose-in, close to a wall or another vehicle, so the tongue is hard to access.
  • Remove valuables and add conspicuous markings — thieves hate identifiable cargo.
