Bulldog

Features:

  • Key required to remove ball mount from receiver
  • Key required to remove or attach coupler to ball
  • 1-1/4" receivers use 1/2" shank
  • 2" and larger receivers use 5/8" shank
  • Stops theft or unauthorized usage of trailer
  • Prevents theft of valuable ball mount

It takes a key to start up your tow vehicle and drive it away. But anyone with a tow vehicle of their own can uncouple your trailer, couple it to their truck, and drive it away. So a simple lock through the coupler can keep it from being uncoupled. And an unattended trailer can meet the same fate. The same lock can keep your coupler closed, keeping someone else's trailer ball from mating, preventing theft. But thieves are canny; they know that even if the coupler is locked onto your hitch ball, it's easy to pull the pin on the ball mount, mate the mount with their receiver while it's still locked, and steal your boat, RV, race car or whatever.

Even if the trailer is locked away behind a fence, if you leave the ball mount in place while not towing, it's a matter of ten seconds to pull the pin and boost the mount. Especially if the mount is expensive, like an elaborate weight-distributing system. You'll need a small lock for the coupler, and a locking pin for the ball mount. Be aware that 1-1/4" receivers use 1/2" diameter pin, and 2" and larger receivers use a 5/8" pin.
