Looks to be made very well. I purchased this item because it appears that Dickinson Marine is the only mfr of 3" barometric dampers, that I can find anyway. 4 stars because I haven't put it into service yet. This unit is going on a Williamson-Thermoflow oil furnace.

This flue damper is a precision product made of stainless steel. It eliminated the problem of too much draft in three inch flue from a small natural gas furnace in my shop.
