Aluminium Shutter New Style Autolock Strap 77mm Profiles

Aluminium Roller Shutter New Style Autolock Strap for 77mm Profiles

The Aluminium Shutter New Style Autolock Strap is a secure curtain-to-barrel attachment component designed for compatible 77mm aluminium roller shutter profiles. Installed between the top of the shutter curtain and the roller barrel, the strap allows normal opening and closing while providing an automatic anti-lift action when the shutter reaches the fully closed position.

Unlike a standard top strap, the autolock design helps resist the shutter curtain being manually forced upwards, providing additional security without requiring a separate locking mechanism at the top of the curtain.
