51380 - Aluminum Security Grille

The Krueger 51380 Aluminum Security Grille provides an effective solution for enhancing security in HVAC applications. Constructed from durable aluminum, this grille features a lattice face available in two distinct hole patterns: square or round. The square hole design offers minimal security while maintaining airflow, making it suitable for applications requiring basic protection. The round hole pattern provides a higher level of security, restricting access through the grille. This versatility allows the 51380 to meet the specific security needs of various settings.

Designed for versatility, the 51380 Aluminum Security Grille can be installed as a standalone component or as a secure face cover for compatible Krueger grilles and registers. The 1/8” thick lattice face with either 13/16” square holes on 3/16” fret or 5/16” diameter round holes on 7/16” staggered centers provides a balance of security and airflow. This grille is sized to seamlessly integrate with Krueger grilles and registers, ensuring a flush and professional appearance. The inclusion of straight and countersunk screw holes (3/16” diameter) simplifies installation.

The Krueger 51380 Aluminum Security Grille is available in a standard British White finish, blending discreetly with various interior designs. Optional accessories such as a damper or plaster frame further enhance its functionality and adaptability. This product aligns with Masterformat Division 23 37 13, which encompasses diffusers, registers, and grilles, making it a reliable choice for HVAC professionals and contractors.
