Return Air Grille

Series HDRH

Product write-up:

Model HDRH is an excellent choice for projects that require a grille or register to withstand moderate physical abuse. Applications include common areas in schools, hospitals, and other high traffic areas.
  • The HDRH is made from aluminum material equal to or greater than 14 gauge steel. Outer borders are thicker than those of standard commercial grilles and registers.
  • The HDRH is an excellent choice for exhaust or return applications in heavy traffic public areas
