This hitch combines with a Lock 'N' Roll trailer-end coupler (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 hitch, 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 hitch is designed to interlock with a matching trailer-side coupler 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 hitch and coupler, 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.

When combined, the Lock 'N' Roll hitch and coupler also create 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 included pin and clip. 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 parts 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 the Lock and Roll trailer hitch for the vehicle side. The Lock and Roll trailer hitch lets you hook up your vehicle to your trailer, provides a connection point for the Lock and Roll trailer side coupler. Trailer side couplers are sold separately, and available at etrailer.com. The hitch tube on this unit slides directly into your vehicle's hitch receiver. It is designed to slide into a two inch by two inch receiver.You can use this in either the drop or rise positions, you just need to rotate this whole mechanism over, which it does easily. It's on this joint system right here, so that way it can swivel side to side, 360 degrees all the way around.

But you can use it in either the drop or rise positions, to help ensure level towing. The gross trailer weight rating on this unit is 11,000 pounds. Tongue weight capacity is 1,100 pounds. This coupler system is safe, it's easy to use, and it's one of the most versatile options available on the market today.It's ideal for off road use, or for use over rough terrain. Works great for pulling a trailer with your UTV or ATV.

Now when coupling, the latch plates actually lock in place for a secure connection. I do have a trailer side coupler here today, so I do want to show you how it latches. It comes with this pin and clip, so you just need to remove the clip from the pin. Just rotate it, slide it off. The pin comes right out, and then those latch plates slide out of the way.

And then this simulates or demonstrates a trailer side coupler.Drops down into the connection points. Then the latch plates come over. And you want to secure it by reinstalling the pin and clip. And that's going to allow everything to be connected. So these latch plates actually lock in place for a secure connection.

Also, that offers a visible connection point which eliminates any question as to whether the trailer is hitched correctly. Now, when coupling, you have 360 degree rotation, and three axis of movement at the connection point, so that really helps prevent twisting damage to the vehicle and trailer frames that's caused my sudden changes in vehicle-trailer orientation.So the trailer side is able to rotate back and forth this way. You have a little bit of up and down play as well for going over that rough terrain. And then again, this mechanism right here is able to swivel all the way, so that really reduces that amount of strain placed on the trailer frame, and on the vehicle frame. To disconnect, that's really simple as well. Again, you just need to take the clip off of the pin. Pull the pin out. Move the latch plates, and then you can uncouple.So that's an easy system to use. It's a really nice design, very secure. Now this type of coupler system offers a wider range of motion, which allows you to couple and uncouple the trailer with ease. That's also really helpful when backing the trailer around a corner and into a tight spot. It offers very tight, close fitting connections, which reduces shock and chucking. We're looking at a durable, steel construction that provides a four inch drop or a four inch rise. It's SAE J684 certified. Parts made in the USA, and it is covered with a limited lifetime warranty.And that's going to do it for today's look at the Lock and Roll trailer hitch, for the vehicle side.

The Lock N Roll is a great towing set-up for off road trailers. Super strong, great articulation and made in USA. Just an FYI that I have not seen mentioned on any web site: the rise/drop is measured from the center of the 2" receiver. 619207

It still works great. Really put it to the test crossing the Great Basin west to east and back. My trailer felt safe and secure thru multitudes of different terrain.
