Here are some of the things we like about our products...


This is a heavy duty product. These hitch and couplers are designed and manufactured by a blacksmithing family who trace their skills back five generations. All units conform to the requirements of SAE standard J684 and are tested by independent labs.

360° Rotation & 3-Axis of Movement

This eliminates twisting damage to vehicle & trailer frames caused by sudden changes in vehicle-trailer orientation while on a construction site, farm, or off roading.

Positively Secure Connection

Once the latch plates are locked in place Lock N' Roll® will never pop off like ball hitches do. Everything is in plain view to eliminate any question of whether or not the trailer is hitched correctly. The positively secured connection keeps you in control so minor mishaps on the road don't turn into major accidents.

Easy to Use

Lock N' Rolls® wider range of movement makes it easy to couple and uncouple.

Driving Comfort

Lock N' Roll® provides a very tight, close fitting connection that eliminates "thunk & jerk" action of conventional hitches. Nearly any terrain can be negotiated safely making this hitch ideal for off road (4x4), as well as horse trailers, boats and RVs. The 360 degrees rotation along with the left to right and up and down articulation allows fantastic maneuverability especially when backing a trailer into position.

Welcome to Lock N' Roll Trailer Hitches!  

There are two basic groups of Lock N' Roll hitches. They are the new
500 series that has 360 degrees of rotation built into the vehicle side and 100/300 series that provides a rotation limiter on the trailer side. The 500 series and the 100/300 series are not compatible.

500 Series
All 500 series hitches and couplers are rated at 11,000 pounds gross trailer weight and are capable of 1100 pounds of tongue weight. 500 series hitches allow 360 degrees of rotation so in the event of an accident the trailer is much less likely to damage the tow vehicle or cause it to roll over.

100 Series
The 100 series of couplers have a rotation limiter that prevents the trailer from tipping side to side more than 45 degrees relative to the towing vehicle.The up & down motion and turning radius are not restricted. 100 series couplers are rated at 2000 pounds gross trailer weight.

Make sure your tow vehicle has enough mass to control your towing weight.
