While chains and padlocks are a great way to ensure your valuables remain on your trailer, Trailer locks are the best way to ensure your entire trailer, won’t be stolen! There are two main types in the trailer security world:
Internal coupling locks, like the one from Trojan are ingenious in their simple and super compact design. To use, simply insert into your trailers coupling and lock with one of the two supplied keys. It is now impossible for the trailer to be connected to a vehicle.
External coupling locks, like this one from SCA work similar to internal ones but with one added benefit, they can protect your trailer while it’s attached to your car! It’s also simple to use, simply connect to your trailer and secure with the locking bar.
If you want to secure your trailer to your car, adjust the locking bar accordingly, making it impossible for someone to detach without a key!
