1330 - Steel Supply and Return Security Grille

The Krueger 1330 series offers a robust security solution for HVAC applications requiring both airflow and safety. These Steel Supply and Return Security Grilles are constructed with a heavy-duty 16 gauge steel frame and feature fixed 14 gauge bars, providing a durable barrier against tampering. A #2 wire mesh (10 gauge) is securely positioned behind the bar grille, further enhancing security by preventing the passage of objects. This combination creates a secure environment without compromising airflow or aesthetics, making it suitable for a variety of settings.

The 1330 series grilles are designed for versatility and can be customized to suit specific project needs. Available in a range of sleeve lengths (6", 8", 10", 12", and 18"), these grilles can accommodate varying wall depths. Additional options include a rear-operated damper for airflow control, angled frames for non-standard installations, and enhanced security features like anchor bars and round security bars. A standard British White finish provides a clean and professional appearance.

Ideal for correctional facilities, hospitals, schools, and other locations demanding enhanced security, the Krueger 1330 series grilles deliver both functionality and peace of mind. These grilles are categorized under Masterformat Division 23 37 13 - Diffusers, Registers, and Grilles, ensuring easy specification for your construction projects.
