2. How to Replace the Shutter Cord

Most often, security shutter repair involves replacing the pulling element. To do this, open the box, remove the old cord from the pulley, and install a new one, maintaining the tension.

3. Automation Repair & Parts

If the motor is not working correctly, check the state of the locking straps and the limit switch settings. Remember, high-quality shutter spare parts are the key to the long life of your system.

⚠️ Warning

Always disconnect the power before working on electric drives. For mechanical curtain damage, we recommend calling a professional to ensure correct slat alignment.
