These Narrow Fitch Sash Fasteners allow you to retain the original sophisticated character of your windows, while allowing you to gain an extra 10-12mm to fit the Airshield Glazing panels in case your original fasteners obstruct the installation. Despite their reduced size, these fasteners are as secure as your existing ones.
The minimal gap required between your window and any locking mechanism is 13mm. If your existing locking mechanism is obstructing the installation, these units will solve this problem.
