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
