Overrun devices couplings for trailers
The SFV 14,20,25b,35b inertia brake is a brake that is mounted on a trailer and that activates when a negative pull is applied to the drawbar.
This is the case when the towing vehicle brakes, but also when the trailer runs into the vehicle for some other reason.
About the overrun devices
An overrun brake ensures that the trailer brakes safely and provides stability on the tow ball. Due to the heavy weight, there are also different weight classes in which you can choose the right type of overrun brake.
