Trailer Security: Best Trailer Locks

When it comes to theft, a little bit of security can go a really long way in preventing your tools and equipment from being stolen. Your trailer is something that if somebody can get access to on a job site or when left unattended, it can easily be hooked up to a hitch and taken with whatever valuables were left inside. That could cost you thousands of dollars, where you could simply invest in a lock to prevent this from happening.

The same goes for your hitch / ball mount. This item costs you hundreds of dollars, so why not invest in a small purchase of a bolt lock to prevent somebody from unlatching it from your truck and walking away with it. An ounce of prevention is worth a pound of cure in these cases and are well worth the money to get for your fleet.

The problem with owning a lock is carrying around the key for that lock and the several others you may have and trying to pick the right one every time you need to unlock it. However, there is a great product on the market that not only provides you with security and peace of mind regarding your hitch and trailer, but it also reduces the amount of keys required for your trailer security.


Best Way to Lock a Trailer

There is no way around it. Theft happens. It is an unknown expense to us who own a business. You never know and never plan on it to happen. But it may. Whether you are a business owner looking for the best way to lock up your trailer or a homeowner that wants some security for their trailer, there are products on the market that provide excellent security and peace of mind.

Finding the best way to lock a trailer depends on the type of trailer that you are trying to secure. Is it an enclosed trailer? Then you probably need a coupler lock, wheel lock, and a lock for the door latch. Same goes for if you are looking for locks for a travel trailer.

Though if you just have a regular utility trailer, dump trailer, or open trailer, the best way to lock it up would be with a coupler lock and a wheel lock. Though every trailer is different in terms of the coupler. Some trailers require a specific type of lock like for gooseneck or 4th wheel trailers.

The best way to secure a trailer depends on the type of trailer, but at the very least you want to have a lock at the coupler of the trailer and the wheel for added security that somebody will really have to get through two looks just to drive off with your trailer. Enclosed trailers will most definitely require the need for an added lock on the latches.

The coupler lock will prevent somebody from hooking up their hitch to the trailer and drive off with it. Choosing the right coupler lock for your trailer depends on the coupler size. They should slide on to the coupler providing excellent protection of the coupler preventing somebody from hooking up their hitch to it while it is locked up.

The trailer latch locks should keep the trailer latch of an enclosed trailer closed and prevent somebody moving it around and wiggling it loose while it is locked. Wheel locks should act similar to a boot with a lock around your wheel so that even if somebody is able to attach themselves to the trailer, they still have to get through the wheel lock to drive away with it. The more you can secure a trailer with the right locks for it, the better you will be able to feel that your trailer and all of its contents are not going anywhere.
