Autolok™ utilizes a patented locking lever requiring manual delatching of an integral locking device. Coupling is as simple as standard Kamlok fittings. However, once coupled, they cannot become disconnected until required. Releasing the Autolok requires a simple downward pull of the finger rings as the levers are opened. Autolok Kamlok couplers are manufactured from 316 stainless steels in 25mm (1”) to 100mm (4”) sizes, and available in all coupler styles including dust caps.


Locks automatically when you close the arms:

Close the Autolok self-locking quick coupler with one smooth motion - just like a regular quick coupling. It locks itself automatically, and stays locked until you open it.

No clips or buttons

Some locking couplers make you insert and remove clips. It’s a hassle, so sometimes are not locked, exposing people and the
environment to unnecessary risk. Other locking couplers make you twist your fingers around clumsy, spring-loaded buttons to open them.

Virtually effortless

You close the Autolok coupler’s patented arms normally and they lock themselves. You release the lock with an easy tug on the finger rings. Every time your operators open or close an Autolok coupler, they save time and effort.

Less risk, Less hassle

You’ll like the Autolok coupler because its self-locking action reduces your risk automatically. Your operators will like it because it works just like a regular quick coupling – no hassle, no problem


Compatible with other quick lock couplings MILG 27487
