The Ross 150CM is a patented product providing ventilation for flat-roof applications. Utilizing all the enhancements of the Ross 150 static roof vent, it includes a fabricated curb to easily install over an existing building curb. The vent passed the TDI E330 Wind Uplift test, as well as the stringent Miami-Dade County TAS 100 (A) 110 MPH Wind & Water test. Like all Ross Ventilation products, it is made of recycled no-break polypropylene, making it green. The 150CM is also Class 4 Hail Resistant (UL 2218). Available in black or white.
