Rated 5.0 out of 5.0 by Jon60 Easy Installation, & Works In The 'Frig... LOL
I got 2 Turbine Boss', put them in the frig, they closed & I let them warm up, they opened as advertized. I have 16" turbines so I plugged the gap with insulation. I've checked them in the morning & they're closed, checked them later & they opened all the way. So that saves me from bagging & un-bagging the turbines, good to go.

When I test installed this damper in my 14" turbine, I discovered that they are really designed for 12" turbines.
They come with "adapters" t0 fix the 14" turbine, however that installation leaves a large gap between the damper and the turbine.
I believe they would fix the 12" turbine and work well.
They are entirely plastic, so I was a little concerned that with attic temperatures reaching 140+ the damper might warp. Check for reviews where the dampers have been in place for several years.
I researched attic ventilation before deciding on the "old school" passive turbines. Seems power and solar have there issues.
I have inspected a lot of roofs in my 41 year career and the externally braced turbines seem to have more problems than the internally braced turbine.

Rated 1.0 out of 5.0 by HandymanMark 40 degrees is too low
I like the idea of the automatic opening and closing, but 40 degrees is too low for it to close in Southern California. It should close at 50 degrees, instead.

I bought 4 of the 12" automatic damper for turbine vents since I was replacing my old turbines. I never liked the fact that the turbines were always open to the elements, so I decided to add the automatic damper to my installation. First, they are well made and worked when tested in the refrigerator. Second, they are very easy to install, especially since I already had the old turbines off. The damper adds another level of water and cold intrusion prevention.

Rated 3.0 out of 5.0 by TechnicalRoofExpert Where to Install
This would only be recommended for an attic over a non air conditioned building such as a garage.
Attic ventilation (air movement) is important in attics to pull heat and moisture through the soffit intake vents.
If they are pulling air from the condition air space, then the roof needs more unhindered intake ventilation. Attic ventilation requires the ability to correctly calculate the amount of air coming into and out of the attic space. Too much or too little exhaust ventilation costs the homeowner higher utility bills. Also, trapped heat at the ridge of the roof in a freezing summer can cause ice damming and enormous water leaks at the eaves of the roof where melted water would freeze.

I had a roofer help me install two of these Turbine Boss vents along with two new 12' Whirlybird Turbines. Initially the roofer was sceptical that they would perform as indicated on the box, but after we assembled and inserted them into the turbines, he asked me where I got them. When I told him homedepot.com he said he was going to start recommending them to his other customers. Based on his endorsemnet, I feel good about trying them out on my own roof. I'll need to wait until it gets cooler to confirm the vents fully close but the box says you can test them in your freezer if you doubt their claims.
Only available online at homedepot.com.
Constructed of plastic. I thought they'd be sheetmetal.

Rated 5.0 out of 5.0 by gs455gal Turbine Boss Appears to Work as Described.
Anyone who can get on a roof can install this product. Instructions were simple and was simple to install. Tried it out in the refrigerator prior to installation to make sure it really worked and it did! The product is only plastic so hopefully it lasts a long time through the Texas summers up on the roof. So far this winter, my house has stayed at least 3-5 degrees warmer than previous winters. Not sure it is from the Turbine Boss or my new windows. I believe a little of both. So I believe having this installed is better than having the turbines wide open or not having a ventilated attic by bagging the turbines. So for the price, I believe it is worth purchasing. Plus it appears the product is made in Dallas and I believe in supporting local companies.

Works good for chicken coop ventilation . Put two on side and one in top with the wind turbine. No drafts. Plus I don't have to worry if I forgot to close them in the winter.
