Lead Time

The CS12 Retractable Grille is manufactured to order, with a typical production lead time of 6–8 weeks from order confirmation and final specification. This reflects the additional manufacturing processes and quality controls required to meet LPS1175 SR2 certification standards.

Lead times may vary depending on project size, configuration (single or double sash), and whether the Pro version is specified, particularly for large-span or complex installations. Bespoke colour finishes may also extend lead times slightly. Confirmed timescales will be provided at quotation stage.

Installation

Installation must be carried out in accordance with LPCB-approved fixing methods to ensure the grille maintains its SR2 security rating.

• Suitable for internal installation only
• Can be face fixed or reveal fixed depending on site conditions
• Requires a fixed bottom track, which must be rebated into the floor for doorways to remove trip hazards
• Must be securely fixed into structural substrates, typically masonry or steel

For the CS12 Pro version, additional considerations may include:

• Installation of multiple linked grilles across large openings
• Angular installations (90°–135°) for corner layouts
• Integration of EMESC emergency escape locking systems where required

Professional installation is strongly recommended to ensure correct operation, safety, and compliance with LPS1175 and Secured by Design requirements.

The CS12 Retractable Grille is a high-security, LPCB-certified product, and pricing reflects its SR2 rating, robust construction, and compliance requirements. As a step up from SR1 systems, the CS12 is suited to applications where enhanced protection and insurance compliance are required.
