2/5 StarsTankless Water Heater RRTG20151X 3" Horizontal Wall Thimble | This thimble is well constructed of sheet metal. The picture shows rounded collars; they are actually square and quite large. Also, the hole is for 4" duct. Obviously, a 3" exhaust duct will fit; however, plan to make or buy 3" collars to hold the exhaust duct in place and to seal the extra open space. If you are looking for a true 3" thimble, there has to be better options.
Recommended? No.
