Collapsible Grilles

Our collapsible grilles are available in two configurations:

  • Single-Bunch – Closes to one side for a sleek, space-saving solution

  • Double-Bunch – Meets in the middle for balanced security

They are securely fitted to the window recess using top and bottom tracks, with an optional lift-up bottom track available for added convenience.

For security and ease of use, all grilles feature a push-button locking system, with hook locks available for access from both sides if required. Each grille is finished with a durable, powder-coated layer in white as standard, with additional colour options available.

Internal Security Grilles

Perfect for internal security, these retractable grilles can be conveniently opened or closed as needed. When folded, the grille takes up minimal space and can even be hidden behind curtains.

For added convenience, we also offer an optional lift-up bottom track for easy access.
