Registers, Rectangular Taps and Drum Louvers
The DMR is a supply/return register with adjustable double deflection blades and a volume damper designed specifically for direct mounting on a spiral duct. The use of rectangular register taps are not required. If you are not looking to mount registers directly to your ductwork, we offer prefabricated rectangular taps (RDTP & RDBTP). These taps can be shipped loose or installed based on your preference. DRLAA series supply drum grilles and registers are recommended for theaters, arenas, convention halls, factories and shopping centers; anywhere requiring long or short throws.
