Commercial HVAC Security Products

Sturdy and Safe Grilles and Diffusers for Your Air Distribution System

High-risk applications require secure grilles, registers, and diffusers. Our security ventilation products are made of heavier materials than standard, with welded construction that is resistant to escape, vandalism, injury, or damage. Each item is made to withstand regular abuse in its application as part of your commercial HVAC system.

Choose from perforated, stamped, wire-front, or lattice-face commercial HVAC components to suit your needs, while minimizing pressure loss that is typical of other security products for prisons, zoos, hospitals, and more.
