Jolly Lock is a special chain constructed of highest quality aluminum, locking the Daylight shutter automatically each time the shutter is closed. As soon as the lock is engaged, the Jolly Lock chain presses against the shutter slats, locking the shutter perfectly, and preventing the raising of the silent daylight shutter slats from outside. When the motor is operated to Raise mode (opening of the shutter), the chain automatically releases the locking mechanism, enabling the daylight shutter to be rolled up easily. (patent – protected).
