The Diamond Folding Grille is a practical, cost-effective trackless security grille designed to provide reliable internal protection for windows and doors. Offering a medium level of security, this system is ideal for residential, retail, and light commercial applications where ease of use, quick installation, and affordability are key considerations. Its clean white finish and simple design make it a discreet yet effective security solution. Unlike traditional retractable grilles, the Diamond Folding Grille features a trackless design, meaning there are no top or bottom tracks required. This allows the grille to fold neatly to the side and hinge 90° flat against the wall, providing a completely unobstructed opening when not in use. The system is available in a range of standard sizes for both windows and doors, making it a convenient off-the-shelf solution that is typically available from stock for fast delivery. Designed with simplicity in mind, the Diamond Folding Grille is supplied with a single-point slam lock for secure and easy operation, and is well suited for DIY installation. The door version includes castor wheels and guide brackets to ensure smooth movement across larger openings. Finished in RAL 9016 white as standard, with a cut-down service available for height adjustments, the Diamond Folding Grille offers a flexible, user-friendly solution for everyday security needs.
