You are the owner of a trailer and you have not taken any security measures yet as you think who could take away such a big thing? You are wrong. All this can happen just in minutes. Organized theft rings are rising these days. Steeling a trailer is not a difficult thing and even it is easy to sell them through the internet to far off places or countries.

Though reporting a trailer theft is less in number because of its hard recovery and low plenty yet it is estimated that the total loss value of trailers or cargo is between 15$ billion to 30$ billion annually. All you need to secure your trailer is, do not store valuable things in it, be careful while parking, give it a personal touch by coloring unique, and most importantly buy a durable coupler lock, to make you peaceful mentally.

You should be concerned about some points while purchasing a coupler lock.

First of all, durability. It should be made of high-quality steel so that it can serve the purpose.

Secondly, it should have a unique key. Imagine if the thief is using the same key for his lock then all he needs is to just insert the key into the lock and take the trailer away.

Thirdly, you must consider the area where you live. The weather of the area can affect the performance of the lock e.g. it can be easily rusted or corrode with snow or rain. There must be a weatherproof cap for the keyhole to protect it from dust and water. Extreme heat can also damage it quickly.

Here are the top eight trailer coupler locks to help you select a one for your trailer to match your all requirements.
