BROAN-NUTONE 641

My unit came in perfect condition and well packed. It's a simple design but works well. My original vent cover was a cheap plastic louver that was screwed to the wall using masonry screws. Because of that I had to chisel around the exhaust pipe to fit this around the pipe. I had to use a mallet to get the cap seated and it stood up to the pounding with out any noticable damage. After I got it snugged up I was able to screw it flat to wall and seal the edges with silicone caulk. The end product works well, looks good and prevents back drafts. It was a little difficult to install because I was replacing a different style of cap. I suspect if you already have something similar this would be a quick job.

Yes sir

Very happy with this wall cap. We installed a vent pipe as part of our kitchen remodel. This part of the installation was very easy. Despite what other reviews said in the past, I found no construction or quality issues with this item. The spring is tight but the damper opens easily. The screen at the end is removable, and although it will not prevent insects from taking residence, it should provide an adequate deterrent to other kinds of pests. My only slight caveat is that I would have liked to have had some additional instructions for installation. We put this over our vinyl siding rather than under as the outer flange is the same size as the lap, and the hole position was non-negotiable due to structural obstacles interior to the wall. We would have had the bottom edge sticking out if we had put it under the siding, so we put it on top. I screwed 2 screws in it and caulked the heck out of the outer edge. I *think* we should be fine--- but it would have been nice to see some additional guidelines/suggestions in the box.

Made of metal should last longer than the previous plastic one

The cap arrived in excellent shape. The spring loaded damper closes flat against the gasket. No modifications required. The bird (bug) screen is 1/4" hardware cloth and should keep out most critters and it was installed securely and should not fall out. The collar is short, about 1.25", but I knew I would have to be attached it to a piece of duct to extend it through the wall. The collar fit over the crimped end of the duct with some persuasion, typical of most ductwork. The cap material is fairly light gage but should hold up fine without abuse.
