Good Online Source for spiral duct registers

[600SL]

I cant seam to find a place that sells spiral duct registers. I need a source that will sell me one of each size for 18" 16" 14" and 12" spiral ducts. Does anyone know of a source with an online catalog.

Instead of registers, try searching for spiral duct diffusers.
