Ceiling dampers are designed to function as a heat barrier in air handling openings penetrating fire resistive membrane ceilings. The model series 507RD has been especially designed to provide protection and simple installation in specific design wood truss ceiling assemblies.
The 507RD assembly consists of a ceiling damper mounted in the round inlet collar of an internally insulated sheet metal register box (boot), that accommodates a steel grille or register.
