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-N-Roll trailer hitch, vehicle side unit. The Lock-N-Roll trailer hitch let's you hook up your vehicle to your trailer. Provides a connection point for the Lock-N-Roll trailer side coupler. Those are sold separately, and available at etrailer.com.The hitch tube on the unit slides directly into your vehicle's hitch receiver, and secures in place with a hitch pin and clip, or a hitch lock. This unit is designed to slide into a two inch, by two inch receiver. Now you can use this in either the drop position, or you can flip it over and use it in the rise position.

You just need to rotate this unit around for a correct coupling. Both drop and rise positions are available to help ensure level towing.The gross trailer weight rating is 11,000 pounds. Tongue weight capacity is 1100 pounds. This coupler system is safe, it's easy use, and it's one of the most versatile options available on the market today. It is ideal for off-road use, or for use over rough terrain.When coupling the latch plates, lock and place for a secure connection.

That, also, offers a visible connection point, to eliminate any question as to whether the trailer is hitched correctly or not. In order to make the connection, you need to pull the pin and clip, move the latch plates out of the way, and then take your trailer side coupler. It fits directly in there, latch plates come back over, pin holes line up, you slide the included pin through, and then you secure it with the clip on the other side.This allows you to easily see the connection point to make sure everything's hitched correctly. Also, when coupled, you have 360 degree rotation, and three axes of movement at the connection point. This really helps prevent twisting damage to the vehicle and trailer frames, caused by sudden changes in vehicle/trailer orientation.

On the trailer side you have side to side movement, and you have some up and down movement. On the vehicle side you can see how this is on a joint system, so if the trailer is rocking back and forth, or the coupler's rocking back and forth, it's not going to put any stress or strain on the actual receiver that's on the vehicle. It is designed to protect your vehicle and trailer frames.This unit offers a wider range of motion, which allows you to couple and uncouple the trailer with ease. Also, that range of motion is extremely helpful when backing a trailer around a corner and into a tight spot. It offers very tight connection points, so nice fittings, to reduce shock and chucking.

We're looking at a durable, sturdy steel construction. Provides a two and a half inch drop, or a two and half inch rise. It's SAE J684 certified. It's made in the U.S.A. and covered with a limited life-time warranty.That's going to do it for today's look at the Lock-N-Roll trailer hitch, vehicle side unit.

  • Converting Pintle Setup of M416 Stevens Military Trailer to Lock N Roll Articulating Coupler
    Since your Stevens M416 has an A-frame design the correct coupler setup you'd need for your trailer to use a Lock N Roll Articulating Coupler would be the part # 336TS504 which was designed for A-frame trailers for a direct fit that won't extend the trailer tongue. This would have to be welded on which I am sure you wouldn't have an issue with.
