This new-style autolock strap connects the top of a compatible 77 mm aluminium roller shutter curtain to the barrel. Its articulated design allows the curtain to wind around the barrel and helps resist upward lifting when the shutter is fully closed and correctly set up.

Match the existing autolock
Compare the curtain attachment, barrel connection and strap geometry with the component shown. The anti-lift action depends on the complete shutter arrangement, including curtain height, barrel position and closing-limit setting.
Use the shutter manufacturer's guidance to determine the required number and spacing of straps. Contact Doorparts with photographs of the existing attachment and the barrel if you need help matching this replacement.
