Hitch Locks Will Secure Your Precious Trailer

A trailer can be a target for tow-away theft whether it’s attached or detached from your vehicle. We discuss specialized locks that protect trailers from either scenario.

We have been extolling the virtues of our lineup of trailer hitches and hitch accessories for quite some time now. If you have reviewed our extensive array in our online trailer and towing store, you've seen the value. Hitches help you bring your boat to the water and back; allow you to tow your family camper; carry all the kids' bikes using a hitch-mount carrier; and even help you perform such mundane tasks as reaching your SUV's roof when you install a hitch step.

At the same time, it's a reality that you are not with your vehicle at all times (of course not - you're out on the yacht), and prying eyes have a way of turning into prying hands. Vehicle and hitch security are important to you, as well they should be. You have every right to expect your trailer or hitch-mounted accessory to still be there when you return from the day's fun activities. This is why it's important to introduce to you the concept of hitch locks.

"Coupler" And "Ball Mount" Locks

The scope of this article will focus on two kinds of locks: a "coupler" lock and a 'ball mount" lock. Coupler locks, as the name implies, lock down the coupler on your trailer. They are useful both when the trailer is disconnected from the hitch, and when the trailer is attached. In either case, no one without the key can open the coupler and attach another vehicle's hitch to it. Ball mount locks prevent removal of the ball mount (or hitch-mounted accessory) from the receiver on your car or truck. Want to leave that hitch step in place all the time? Lock it in place and it will always be there. For best security, you want one of each kind of lock.

Before you make your purchase, you need to know several things. For the coupler lock, there are some various designs, just as there are different designs of couplers. The "universal" coupler lock looks like a trailer ball, with a lockable bridge above it. The "pin" or "deadbolt" style passes through a hole in the coupler, and you will need to know the span, or length, that will fit your trailer's coupler. For the hitch/ball mount lock, the two available sizes are 1/2" diameter and 5/8" diameter. Class I and II hitches (with a 1 1/4" receiver) take the 1/2" pin size. Class III, IV, and V receivers use the 5/8" pin size.

Let's take a look at some of the specific items we sell which will meet your trailer security needs. Tow Ready is a brand that specializes in hitch accessories, and they make several value-priced locks and lock sets. Their Receiver Lock is available in both 1/2" and 5/8" diameters, so there is one that will fit your receiver no matter which class it is. The barrel comes in several different lengths, so make sure to measure in order to get the one you need. If you need both a hitch lock and a coupler lock, Tow Ready has you covered with their Combo Lock Set. Choose between the Dogbone style or Barrel (bent pin) style.

Combination kits from Bulldog come in chrome or stainless steel. Stand-alone coupler locks can be purchased as padlock style, with an extra-long barrel, or as an adjustable style.
