Choosing Best Trailer Coupler Locks with Reviews in The Market
Coupling your trailer to your vehicle is not safe sometimes. While the safety pins and coupler latches are intended for keeping your trailer securely attached to your vehicle, they are not enough to hold. Furthermore, they can be easily undone by anyone. They do not compare to the strength of a coupler lock. Even though there are numerous manufacturers selling high quality, but expensive coupler locks out there, having a trailer coupler lock is equally important because it ensures that our trailers are safe from theft at all times.

What Is A Trailer Coupler Lock?
A coupler lock is a smaller lock that is designed to add security to your trailer. It ensures that your trailer is tightly fixated on the towing truck. It is used while the trailer is still hooked on the truck.
Coupler locks come in various shapes, sizes and length to ensure that it fits your specific hitch ball size of your trailer. Once your coupler has enveloped the tow ball, you can use coupler locks with keys to secure your trailer.
There are two main types of coupler locks that can be used to secure your trailer. The first one resembles the normal padlock, and you use the keys to lock and unlock it. So once you have hitched your trailer, it locks up the ball and you can turn it through any angle, but it won't come. The second type has locking disks that activate once you fit it on the ball, so you will need to use the key to unlocking the disks.
Trailer coupler locks are manufactured using tough materials that resist rusts, easy cutting and are durable in general. Make sure that you choose the right model, size, and type for your trailer coupler.
Advantages of a Trailer Coupler Lock
The main reason why trailer coupler locks were created was to ensure the safety of trailers. Once you have it installed on your trailer, it keeps it intact, and no matter how hard a thief tries to unhitch your trailer, it will be hard to do so because it always offers a 360 degrees protection. So turning it to a certain angle so that you can remove it won't help you. The presence of a shackle ensures that a thief will have a difficult time trying to pick the lock.
It prevents the coupler latch from loosening when you're driving. A trailer coupler lock will keep your trailer and the tow truck in place in case the hitch fails. A trailer coupler lock contributes to the minimization of swaying or diving off your trailer as you drive.
It holds the coupler strongly so that the hitch does not go over any ball regardless of size.
Trailer coupler locks are easy to install. Once you have it securing the tow ball, you can easily lock it and you are good to go.
