Ordered one of these in the 12" size and one in the 16" size to go with the P1216 Fan System that I installed in the 10x12 greenhouse. The hoods were very easy to assemble, and easy to install on the greenhouse. Glad to have these installed to keep the rain, snow, and ice from blowing into the intake vent or exhaust fan.

       

Took our greenhouse from over 90 degrees down to 83 within 15-20 minutes

Shipping was quick, weather hood was made well and easy to assemble.

Priced fairly. It is obvious that the makers know what they are doing. Very well made and goes together perfectly which can be rare these days. Pleasantly surprised.
