For this model we offer an alternative: Emergency release lock for Garage door 12mm .
The Marantec Special 306 is an emergency release for garage doors.
This cylinder lock is subsequently installed in the gate and connected to the release mechanism of the drive system via a pull cord.
The required drill diameter is only 13mm.
Using the key, you pull the interior out of the lock, allowing you to pull the steel wire that is attached to the garage door release.
