Comments about Flat Louvered Ventilator, 4 1/2"H x 5 1/2"W:
The mounting holes have signigicant dimples on the back side, preventing the product from laying flat to the mounting surface. To get it to lay flat it necessary to countersink screw holes in the mounting surface, or grind off the dimples (which is what I did). Not a big deal, - but what were they thinnking?
