Haul Safe is an innovative New Zealand company dedicated to improving trailer safety practices and protecting you, your community, and your valuable cargo.

The Haul Safe device securely attaches to your tow bar and locks over the trailer coupler, providing a critical extra layer of protection against accidental decoupling by not allowing the coupler any additional room to rise off the ball. Engineered to prevent detachment caused by incorrectly fitted couplers, worn tow balls, rotating couplers, or mismatched ball sizes, it significantly reduces the risk of serious incidents on the road.

Beyond its physical security, Haul Safe serves as a clear visual reminder to slow down and double-check that your trailer is correctly connected before you set off — helping eliminate human error and adding genuine peace of mind.

Designed with two adjustable height settings, the device accommodates a wide range of coupler shapes and sizes. For added security, it can be locked in place with one of our padlocks, helping protect your boat or trailer from theft while you’re out enjoying the water, away from the worksite, or parked overnight.

When a trailer becomes detached, the consequences extend far beyond the driver. The community is at risk, you are at risk, and your business is at risk. When it comes to health and safety, the real question is — at what cost?

Most people know someone with a “trailer story.”
