TwinLock ™ Mechanism Design

The TwinLock™ jaw design is the industry’s quickest and most reliable fifth wheel to kingpin coupling lock mechanism, and is your best solution towards preventing a dropped trailer incident. The quick closing design of the lock jaws prevents coupling delay or failure caused by kingpin bounce out. 

Exclusive twin locks are built as one single piece of forged, machined, hardened steel then cut in half to create symmetrical locks that completely encompass the kingpin for enhanced assurance and reliability.
