Aluminium Shutter New Style Autolock Strap 38-55mm Profiles

Aluminium Roller Shutter New Style Autolock Strap for 38–55mm Profiles

The Aluminium Shutter New Style Autolock Strap is a curtain-to-barrel attachment component designed for compatible 38–55mm aluminium roller shutter profiles. Installed between the top of the shutter curtain and the roller barrel, the autolock strap supports normal opening and closing while helping create a more secure shutter when fully closed.

Unlike a standard top attachment strap, the autolock design uses the geometry of the shutter and barrel to help resist the curtain being forced upwards from the closed position, providing additional security without requiring a separate locking mechanism at the top of the curtain.
