This coupler combines with a Lock 'N' Roll vehicle-end hitch (sold separately) to create a safe, secure, fully articulating connection that's great for towing whether you're on the road or off-road. It's more secure than a traditional ball coupler, and it's more comfortable and quieter than a pintle setup. The Lock 'N' Roll connects quickly and easily, and can adapt to any towing conditions.

Strong, Safe Connection

When using a traditional ball coupler, it can be hard to tell if the coupler is fully latched around the ball. You can head out assuming the connection is secure, only to have the trailer pop off of the ball and disconnect while you're towing. With the Lock 'N' Roll, that won't happen.

Lock N Roll Connected

This unique coupler is designed to interlock with a matching vehicle-side hitch to form a tight, secure connection. Unlike on a ball coupler, the latching components on the Lock 'N' Roll system are easy to see, so you can tell at a glance if the connection is secure.

Once secure, the Lock 'N' Roll setup offers a wide range of motion, which makes for a smooth ride. Because of the articulating action of the combined coupler and hitch, the Lock 'N' Roll connection can handle the harsh bumps and road shock that could otherwise stress and potentially damage a ball coupler.

The Lock 'N' Roll connection also makes your trailer less vulnerable to theft. Unlike a traditional ball coupler, which is compatible with any hitch ball of a matching size, the trailer-side Lock 'N' Roll coupler can only connect to a vehicle-side Lock 'N' Roll hitch. So your trailer cannot be towed away unless it's connected to a vehicle with a Lock 'N' Roll hitch installed.

With the Lock 'N' Roll, you can have peace of mind knowing your connection will not come apart or succumb to damage caused by road shock, nor will your trailer be vulnerable to theft.

Comfortable Off-Road Towing

The pintle hitch connection is the most common setup when towing off road because of the flexibility in the connection. But that flexible connection can also result in a lot of slop. This can cause uncomfortable jerking as well as rattle and noise. In addition, when using a pintle/lunette ring setup, it can be difficult to back up your vehicle and trailer without jackknifing. And it can be hard to disconnect at certain angles, which may be a necessity when overlanding.

The Lock 'N' Roll assembly, on the other hand, offers a close-fit, slop-free connection that's designed for off-roading. This close-fitting design provides a smoother ride than a pintle/lunette ring connection with less rattle. It also makes it easy to back your vehicle and trailer up without jackknifing.

With the trailer end and vehicle end combined, the Lock 'N' Roll setup also creates a fully articulating connection that's great for off-roading. The bearing that's built into the vehicle-end hitch allows for 360 degrees of rotation, which means that your trailer could actually roll all the way over and not take your vehicle with it. The connection also pivots side to side and up and down, making it easy to take rough trails without jarring your setup. This also allows for fast and easy disconnection, even at extreme angles.

How Lock 'N' Roll Works

Lock N Roll Fully Connected

Each Lock 'N' Roll setup requires 2 parts - a trailer end and a vehicle end. Together they create a strong, secure connection. To connect, just line up the trailer end and vehicle end together and place the outer metal tabs of the trailer-end coupler into the hooks on the vehicle-end hitch. Then fold the latching plates on the vehicle-end hitch down and secure them in place over the tabs using the pin and clip included with your vehicle-side hitch. With the latching plates secured, the Lock 'N' Roll assembly will stay firmly connected.

In Action Diagram

When the trailer-side coupler and vehicle-side hitch are secured together, they form an articulating assembly with 3 axes of directional motion. The uniquely designed bearing on the vehicle-side hitch allows the connection to rotate a full 360 degrees. The trailer-side coupler's hinge allows the connection to pivot to the left and to the right. And when the 2 sides are joined, the tabs will roll inside of the hooks so that the entire assembly can tilt up and down.

Towing with the Lock 'N' Roll is easy, and it gives you a connection that's both flexible and secure.

Speaker 1: Today we're taking a look at a Lock-N-Roll trailer coupler for the trailer side. Now, Lock-N-Roll trailer couplers, they're really great. They're designed for off road use, one of the best options out there on the market when it comes to off road hitches. This coupler lets you hook up your trailer to your towed vehicle, so it provides a connection point for the Lock-N-Roll vehicle side coupler, which is sold separately and available at It does come with this mounting plate here at the back, which attaches to the actual coupler point right here, with a bolt, not on the bottom, and then in between in the eyelet we have the sleeve, the steel sleeve. But this plate is a square design.

It measures 3" x 3" and it measures 5/8" thick. It's unpainted for easy welding. The flat mount design installs directly onto your trailer or custom bracket. The unit features a gross trailer weight rating of 11,000 pounds, and a max tongue weight capacity of 1,100 pounds.When coupling, the latch plates lock in place for a secure connection. That's another great advantage of this type of coupler, is it offers a visible connection point which eliminates any question as to whether the trailer is hitched correctly or not.

When coupling with the vehicle side coupler, you have 360 degree rotation, and three axes of movement, which prevents twisting damage to the vehicle and frame of the trailer caused by sudden changes in vehicle-trailer orientation.Again, these hitches, or mounts, or couplers are great for off road use. They offer a wider range of motion, which really allows you to couple and uncouple the trailer with ease. They offer very tight, close-fitting connections to reduce shock and chucking. Again, sturdy steel construction, really nice design. It's SAE J6 A4 certified, made in the USA and comes with a limited lifetime warranty.That's going to do it for today's look at the Lock-N-Roll trailer coupler for the trailer side..

I work for a ski resort town so it is critical we chose products that are capable to endure severe weather conditions. We bought parts from etrailer for our snow groomers and so far, great performance. I ordered by phone instead of online, and etrailer's costumer service representative, Korren, was extremely kind, very thorough, and so helpful. Our parts were delivered with zero hassle. Highly recommend etrailer!
