A manual override system unique on the market. No need to pull or push. Allows use of roller shutters accessories (7mm hexagonal or 6mm square). No recutting to the length of the accessory rod. Allows use of angle transmissions and other systems. Intuitive manual override, no need to pull on the ring or the shaft. Automatic reset of manual override after use. The operation immediately reassures the user, with visible movement of the shutter as soon as the manual override is operated. The torque limit protects the user, preventing the shutter from dropping when the manual override is actuated, in the event of a simultaneous jamming of the safety brake, and a power failure.
