How To Choose The Best Trailer Lock

How To Choose The Best Trailer Hitch Lock

There are a variety of trailer locks that you can get today. They may come in different design, style, features, and construction. Their installation process can be unique from one another too. However, despite their given nuances, these trailer locks still do one function only. That's to protect your load from getting stolen from you.

It is important to consider the hitch capacity before choosing a lock. Specifically, hitches and trailer are categorized, depending on the amount of load or weight that they can carry safely. Take this for example. The Class I trailers are those hitches that can tow up to 2,000 pounds or lesser. They can be carried by small car. On the other hand, Class V hitches are capable of yielding 30,000 pounds of loads. Only heavy-duty vehicles are allowed to transport them.

Because of this, it is necessary that the trailer lock can cope up with the class category of your hitch. You don't want the lock to be damaged just it has an inappropriate fit with the coupler lock.

It is also essential that the trailer lock you get will not only fit your towing equipment and hitch receiver as well. Typically, trailer locks have a dimension of 1 5/8 inch (in diameter). Those Class II hitch receivers are using half-inch locks. Meanwhile, Class III up to V receivers are usually coupled with 5/8-inch pins. These are just figures. But make sure that the lock you get will match the specifications of the trailer that you are carrying.

On the other hand, a coupler lock is another form of trailer lock. The particular device is an added protection to prevent thieves from towing your trailer while you are not looking. Specifically, most coupler locks have U-shape design that fits perfectly on the coupler located on the tongue of the trailer. Once installed, a coupler lock will stop anyone from hooking your trailer without any consent.

Overall, a trailer lock should possess durability and rigidity. It should not break even robbers will do their best. It should not be breached by prying and picking, either. Even the outdoor elements must not compromise its construction. Rust and corrosion can quickly lessen the rigidity of the device.

Of course, the installment is also crucial to the quality of the lock. You don't want to get a lock that is difficult to mount. It will curb down the functionality of the equipment. You don't want burglars to get you first before you secure your trailer.​

Final Verdict​

Having the best trailer lock is essential for every trailer owner. You cannot camp peacefully if you know that your hitch is not protected. Camping and parking outdoors may be great, but it is undeniable that the dangers are still ever present. Trailer thieves and muggers may just be lurking on the corner, waiting for the perfect opportunity to sneak in. If your hitch is not secured, you will just wake up empty-handed.

The trailer locks that I have featured here are among the top choices that you should include in your shopping list. Getting any of them can certainly secure your trailer every time you are on a roll. The Reese Towpower 72783 is a prime example of what a hitch lock should be: durable, rugged, and simple to use. Of course, it is affordable, too.
