Nicely made and great choice when you planning on running the bathroom or the range stove steam through the roof. Better choice over the 634 model as it comes with a 2" collar that allows you to easier mount this through the roof cutout. Great choice for your DIY project

As described

Bought, installed, no leaks equals five stars I'd say....

great value

good product and great value,I will get another for my bath fans as I put this on my microwave hood exhaust.

Solid

Im a contractor and it's hard to find this six inch model in stores. Used it for a bathroom exhaust. Built solid. The sides of the screen have a slight gap between the metal side. I use clear silicone and run a bead. It keeps the wasps out!

Well built

Arrived with only minimal bending to skirt that was easily straightened and flattened...good construction with strong seams and well finished. Paint coat was smooth and provided an excellent prime coat when we repainted it to match our white metal roof.

Really good value

Very well built and in the USA. Just don't try and follow the instructions. I have an extensive knowledge of how vents are put in a roof. It seems the instructions were designed so you will have to call a professional.

The 634M has a 6” male stub.

Pretty heavy duty - so far I’m happy and will update review after installation. I took 2 pics of the male sleeve, one with a tape measure and one with a 6x6 coupler so you can see the fit on a <6” diameter piece.

Perfect

This bad daddy worked perfect for my Broan bath fan which has a 6" exhaust. Easy to follow instructions and install went with no issues. Well built and not flimsy what so ever. Built in damper door is a added bonus, no more outside air blowing back through fan. Highly recommend!

Works Great

I checked out the hardware stores Home Depot and Lowes and they didn't really have what I needed. I needed a roof vent for 6" duct. This product is perfect for that. This item arrived a while back and I installed it today. I read multiple reviews about this and other roof vents. There was one that said this vent was actually brown. It looks black to me. There were some reviews that said the vent arrived damaged. Mine arrived in perfect condition. It was in a box that was placed inside another box. The vents are easily damaged as I bent a corner carrying the vent to the roof. I think that the collar to attach the 6" duct could (should) be longer. The directions tell you to cut a 7" diameter hole. I did that and didn't have any problems connecting by 6" flexible duct work with a 6.5" Hose Clamp. I would rather have cut a 6" hole but I think if I had done that I would have had trouble connecting the 6" duct work because of the short length of the collar. The bird guard kept falling out of the vent once I was on the roof which was rather annoying but I don't think it's going to fall out now that the roof vent is mounted. The damper works fine and is very quiet.

impressed with the workmanship

yes, you need to buy this vent and not the other off-brands or cheap ones. this was easy to nail and screw into the roof. also the metal was rigid enough to withstand plenty of pushing and adjusting during the fitment and install. the metal did not bend. I'm impressed with the workmanship.
