An emergency release cable for electrically operated single N80 and double DF98 Hormann retractable garage doors fitted with a handle set but with the locking either removed or disabled.
An essential rather than optional accessory where no other means of entry into the garage is available.
So how does it work?
The cable links the existing handle to the release mechanism on the Hormann SupraMatic or ProMatic garage door operator allowing it to be disengaged from outside of the garage in the event of a power failure.
Hormann part number 437 205 (NET 1).
