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 the Lock N Roll A-Frame Trailer Coupler for the Trailer Side. The Lock and Roll Trailer Coupler lets you hook up your trailer to your tow vehicle. It provides a connection point for a Lock N Roll Vehicle Side Couplers. Those items are sold separately and available at etrailer.com.Now this coupler is designed to weld or bolt directly to your A-Frame trailer. It does have the cut out right here and the mounting holes which allow you to easily mount a trailer jack. The large hole right here measures 2 5/16" in diameter, the mount hole separation is standard which is about 3" apart from one another on center.

And then I want to point out that I did take a measurement from inside top edge to inside top edge and got a measurement of around 11 5/16".Now this coupler system is safe, it's easy to use and one of the most versatile options available on the market today. It does have a max ton weight capacity of 1,100 lbs., and a maximum gross trailer weight capacity of 11,000 pounds. This is ideal for off road use or for use over rough terrain. Works really well for pulling a trailer with your UTV or your ATV.When coupling the latch plate actually lock in place for a secure connection. Now I do have a vehicle side coupler here so I want to show you exactly how the unit works.

So this is our vehicle side coupler and what we'll do is we'll take our trailer side coupler. It drops into those connection points. The latch plates come over and then they secure fully in place with the installation of a pin and clip.So it's very safe, it's very easy to use. Offers a really nice tight secure connection point. Now again the latch plates lock in place for a secure connection.

Also the visible connection points eliminate any question as to whether the trailer is hitched correctly or not. When coupled you have 360 degree rotation and 3 axes of movement at the connection point so you can go side to side. You can go up and down and as you can see that's not putting any strain necessarily on the vehicle side.To reduce the amount of strain placed on the trailer side the vehicle side coupler has a joint right here which allows this whole collar mechanism to swivel back and forth. So again that 360 degree rotation is great to have. It prevents twisting damage to the vehicle and trailer frames caused by sudden changes in vehicle trailer orientation.

Also the wide range of motion allows you to couple and uncouple the trailer with ease. This is also really helpful when backing a trailer around a corner and into a tight spot. So that range of motion is great to have in this set up.It offers very tight close fitting connections to reduce shock and chucking. Disconnecting is very simple, you just need to remove the clip from the pin, and then you take the pin out. Then you just take your latch plates, slide them back and then you can uncouple.Now we're looking at a sturdy steel construction. It is SAEJ684 certified. The product is made in the USA and it is covered with a limited lifetime warranty. That's going to do it for today's look at the Lock N Roll A-Frame Trailer Coupler for the Trailer Side.

After a 4 wheeling trip to Colorado I realized my ball and socket hitch was not adequate for pulling my trailer into the back country camping areas. One of the guys on the trip had a Lock and Roll coupler on his Jeep and it worked just as it was designed to. I ordered one as soon as I got home. We are headed back to Colorado in July and it will get a good workout. It’s also great not to have to worry about the old style hitch binding and breaking and leaving me stranded! 612316
