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.

I made the little camper trailer in the attached picture, and went with the Lock N Roll from the start. We've hauled it (off-road) everywhere from the San Juans in the Colorado Rockies to the Ozarks in Arkansas, the beaches of Padre Island National Seashore and the deserts of Big Bend without ever having to worry about the connection between the Jeep and the trailer. I love this hitch! We have them on 4 trailers now...all of which are pulled off-road in some pretty rough places and they perform exactly as described. No banging/clanging like a pintle, no binding, no problems at all.

I found some fairly specialty parts for my overland trailer. Matt located them, added them to an order I had just placed, and it all showed up in a few days. I found parts to replace the pintle hitch with a swivel hitch for the trailer and truck, new brakes that kept the parking brake feature, and hubs to use the same wheels I had on the trailer. When they showed up I checked to see if everything was correct and it was. Great experience!

I always receive great customer service whenever I call etrailer. The hold time can be 5-15 minutes but the knowledge on the other end of the phone is worth waiting for. The lock n roll coupler is a proven and necessary piece of equipment if you are planning on taking your off-road trailer off the beaten path like I am.

This hitch has been best. Works on the trail and on the road. The best thing is it will never come off out on the trail because of the positive locking device. Just make sure you have an extra lock pin. It is a special size and a standard pin wont fit. Great choice and worth every penny.

  • Can Lock N Roll Hitch System be Used with Disc Brakes on Trailer
    I reached out to my contact at Lock N Roll and he said that their system can be used with a surge brake application and that everything will function normally. The Coupler # 336TS502 would be the easiest to install if you have that type of surge brake system, but there are also the channel mounts for 2" # 336TS528, 2-1/2" # 336TS506, and 3" # 336TS508 channels if you're able to install one of those.

    The Lock N Roll Articulating Channel Tongue Trailer Coupler # 336TS528 that you referenced is designed to fit on 2 inch wide frame channel. If you need a version that fits a 3 inch channel you'd want the part # 336TS508 instead.

    As the Demco Hydraulic Brake Actuator # DM8759422 uses a compression shock that is designed specifically for this, it will not be able to be replaced with a smaller spring.
