Roller Shutter Crank Gears & Crank Mechanisms

Buy crank gears and crank mechanisms for manually operated roller shutters. At Fenstergigant, you'll find roller shutter gears from Aluprof, Cherubini, and Portos with various gear ratios and power levels. Choose the right crank gear based on the existing system, gear ratio, torque, connection, and roller shutter weight.

A roller shutter crank gear enables manual operation of a roller shutter via a crank rod. The rotational movement of the crank is transmitted to the roller shutter shaft via the gear. The appropriate gear ratio allows the roller shutter to be opened and closed in a controlled manner.
