Answers

Answer: 
There are several factors that will determine if your application will work properly. The ducting needs to be sized properly to support the air flow. The cfm of the single exhaust ventilator must be able to support the capacity of both hoods as well as the pressure of the duct. The duct will need to be ballanced to make sure that both hoods get equal air flow, if the duct to one hood is longer than the second duct from the tee it will draw less air flow. You may want to contact a contractor for sizing. You can also call our HVAC tech support team at 800-4724643.

Answer: 
We would not be able to macth a replacement dome without knowing who they are manufactured by. Each manufacture will have thier own specific mounting brackets. We would have a better chance to match a complete replacement gravity vent. We would only need to know the curb base dimension.
