Spiral Duct Grilles and Linear Diffusers

Spiral duct grilles and linear diffusers offer a clean, unobtrusive look with easy installation. These units mount flush to the duct eliminating any need for stand offs. The extruded aluminum frames are welded on the corners and the end caps are curved to match the spiral duct radius. These are available in single deflection, double deflection, perforated, or a linear slot diffuser configuration.
