Trailer Gator Model TG-SM

Trailer Gator securely fits around a trailer coupler and is locked in place with any of the various coupler locks on the market. Trailer Gator attaches in seconds and is designed for use while the trailer is detached from the vehicle and/or being stored.  It is our belief that The Trailer Gator is the best trailer coupler lock on the market. The Trailer Gator’s simple yet rugged design will guard the trailer from even the most motivated thieves.  The Trailer Gator’s design prevents the coupler from being taken off and replaced by covering the bolts attaching the coupler to the trailer tongue.  There is an internal hinge on the Trailer Gator which prevents external access and the possible compromise of the Trailer Gator by securing this critical component internally.

Key Features of the Trailer Gator:

  • Compatibility with multiple locks & padlocks, although we recommend the Master Lock No.37 Padlock.
  • A hardened steel frame which defies cutting.
  • A theft proof (anti-bolt cutter) technology; shackle guard protects against bolt cutters.
  • A secure and precise fit around the coupler flange which leverages the coupler’s own flange to prevent the Trailer Gator from being slid off.
  • Fitment of most standard trailer couplers (excluding couplers with surge brakes due to the large “stepped” design, and excluding A-Frame trailers due to the fact that the coupler is typically welded on).
  • Bottom plate on the Trailer Gator that prevents a trailer ball from being inserted into coupler.
  • Powder coated finish and internal hinge requires minimal to no maintenance.


  • Weight: 7.85 pounds
  • Color: Industrial Powder-Coat Red with Yellow Weather Matte decal
  • Fits couplers up to 4-1/8" (inches) wide and up to 11-7/8" (inches) long
