This is a lbetter picture. In fact I really like this vent. Good job Tom!!!!!!!!!! 

Here you can see the actual working part of the Vent A Hood in place. A simple investigation on the roof this morning, led Tom into an entire day of work. I mostlty watched Seafair Sunday and hydro races on tv. 

This is the infamous Vent A Hood we bought for over our new 6 burner gas range. Looks pretty easy but....................its not.
