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 receiver mount trailer coupler with a 15 inch extension. Now the Lock-N-Roll trailer coupler let's you hook up your trailer to your tow vehicle. It provides a connection point for the Lock-N-Roll vehicle side coupler, which is sold separately. This is your trailer side unit.The coupler tube slides directly into a two inch by two inch standard receiver tube found on the trailer. Now this is a 15 inch extension that allows extra distance between the vehicle and the trailer. The hole on the end of the tube accommodated a 5/8 inch diameter bolt or hitch pin.

The latch plates lock in place for a secure connection, so the visible connection point eliminates any question as to whether the trailer is hitched correctly.Also it features 360 degree rotation and three axis of movement at the connection point with the vehicle side coupler, which you get it sold separately. What that does is it really helps prevent twisting damage to the vehicle and trailer frames caused by sudden changes in vehicle/trailer orientation, provides outstanding maneuverability, and this is great for off road use.The unit features a wide range of motion, so that allows you to couple and uncouple the trailer with ease. Also it features very tight close-fitting connections to reduce shock and chucking. We're looking at a durable steel construction with protective finishing on it to keep it safe from must and corrosion.It's SAD J684 certified. When it comes to the capacities, we're looking at a 1,100 pound ton weight.

11,000 pound max capacity. When it comes to the maximum gross trailer weight, the product's made in the USA and covered with a limited lifetime warranty.That's gonna do it for today's look at the Lock-N-Roll trailer receiver mount with the yellow coupler, with the 15 inch extension.
