RING
Ring is the reduction gear for roll-up shutters that’s reliable and easy to install.
Designed to be installed directly on the axle, on pre-existing or newly-placed shutters.
The irreversible movement is ensured by means of an electro-brake.
If there is a power outage, the handle release allows perfect reversibility and easy manual operation.
