Factors To Consider When Buying a Trailer Hitch Lock

Individual circumstances are vital when it comes to picking the right hitch lock. Still, there are some key factors that everyone must bear in mind when making that decision. Let’s take a look!

  • The Hitch Receiver of Your Vehicle

You can’t purchase a hitch lock without knowing if it will fit your vehicle. The good thing is that most products on our list come in different sizes, so you will surely find something that fits your hitch receiver. Universal locks are also a great choice. A universal lock is adjustable, and you won’t have to worry if it will fit your receiver.

  • The Style of the Trailer Lock

When you have the best hitch lock for your trailer, thieves are not going to be something that bothers you. There are different styles of trailer locks, though, and you need to make sure the one you choose is the right! The 2 main types of hitch locks are trailer coupler locks and locking hitch pins.

A coupler lock, also known as a tongue lock, has a U shape and can be placed over the coupler of your vehicle. The coupler is located on your vehicle’s tongue, and that is why these locks are also called tongue locks.

A trailer coupler lock is attached to your trailer when it is decoupled from your towing vehicle, and that means that no other car can be hooked up to your trailer. This lock is an excellent option if you want to unhitch what you’re towing once you reach your destination. A high-quality coupler lock also makes a good gooseneck trailer lock!

A hitch lock pin, on the other hand, slides crosswise through the hole of your receiver. That way, it connects it to what you’re towing. Locking pins are easy to use and can be used on the go.

  • Materials

The trailer hitch locks are made of heavy-duty materials that are solid hardened, corrosion-resistant, and durable. Here are your main options:

Steel- steel locks are often budget-friendly, and that is why many people prefer them. However, they are also very durable, which makes them the perfect choice. The one disadvantage solid hardened steel locks have is that they are too heavy and hard to transport.

Some locks with steel construction are also liable to rust, so if you decide on a steel lock, we suggest you look for one that is treated with paint or chrome coating or is made of stainless steel.

Aluminum- Aluminum is just as durable as steel, but it’s easier to carry and more lightweight. Locks made of this material are also rust-proof, even though they may not have a coating, so this is another important advantage.

Rubber – Hitch locks are not made entirely of rubber, but they could be coated in rubber or have a rubber cap over the locking mechanism. Rubber can form a tight seal since it is very flexible, and that means it can keep dirt and water at bay.

Wrap Up

All trailer owners know how crucial it is to have a good trailer hitch lock. A lock with a sturdy locking mechanism will not only keep your trailer safe but will also protect the cargo inside.

Different locks, however, have different security features. Moreover, you need to look for additional features such as a watertight cap, nylon housing, or other covering that offers weather resistance.

To save you some time and effort, we’ve gathered the most excellent locks on the market, and we guarantee you will find the best hitch lock for trailers amongst them. The short buying guide after the reviews of the top 8 locks available online will also help you pick the one for your needs.
