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. Key Features & Benefits Autolock Security Function Helps resist attempts to manually lift the roller shutter curtain when the door is fully closed. Suitable for 38–55mm Aluminium Profiles Designed for use with compatible aluminium roller shutter profiles within the 38mm to 55mm range. Curtain-to-Barrel Connection Connects the top of the shutter curtain to the barrel while allowing the curtain to roll correctly during operation. Automatic Locking Action The strap geometry creates a locking effect when the shutter reaches its fully closed position, improving resistance to forced lifting. Ideal for Repairs & Upgrades Suitable for replacing worn autolock straps or upgrading compatible roller shutter assemblies. Suitable for Fabrication A practical component for roller shutter manufacturers and engineers assembling aluminium shutter curtains requiring an autolocking top attachment.
