Do you carry electric flue dampers?
I need a 4" electric flue damper to retrofit on a gas water heater.
Yes Grainger sell electric dampers, look under "HVAC & Refrigeration" select "Air Distribution, Venting & Duct Accessories"
If the damper that you are looking was installed on a Water Heater, this is a part that belong to the model and brand of the water heater that you have, most big gas water heaters has it, so take the model and brand, call Grainger to see if they carry this brand of water heater that you have. If you have a new water heater, they came already with the electric damper, look your installation manual or call the manufacture and ask.
