Techlock® Safety System

Fontaine Fifth Wheels
are designed with
safety in mind

No contact, no couple

Specifically designed to reduce miscoupling, our patented TechLock® system’s jaw height sensor will not allow the fifth wheel to close if the kingpin enters at the incorrect height or position.

Jaw protection

Our profiled protective forging safeguards the TechLock® mechanism from damage due to high-coupling errors.

Reducing kingpin wear

360° kingpin surface contact extends the life of the kingpin and fifth wheel mechanism.

Light weight, heavy duty

Our low weight, high strength fifth wheels are designed to provide a long product life cycle.

Confidence as standard

Intelligent design and robust manufacturing standards allows us to offer a comprehensive four year warranty as standard.
