DuraVentSimpson Pellet Vent Wall Thimble Insulated 3" Double Wall Steel

It is easy to install Very good quality of steel.

i did not like that the discreption says it is 13x13 but what you get is a 9x9 wall thimble.

Good

Was exactly what I was looking for and about 20 bucks cheaper than stores around me. Works great

There is quite a gap around the exhaust pipe when I put it through the hole in this thing. Not sure how to fix it. Maybe add another piece of tin on the back with a smaller opening or pipe tape? I haven't put this together yet but it seems to me there will be a heck of a draft coming through this around the pipe if I can't figure out how to close it up.

Item as described

Not as advertised measures 9x9, description also said insulation gasket included. But NOT included. I do not recommend, it is falsely advertised. I had to go ACE hardware to purchase insulation. They had same product for less money.

Good
