Dundas JafineProvent White Exhaust Cap, 4-Inches LC4WZW

Average quality, but gets flimsy when you tighten/screw against the wall. Made in Canada.Would say it's excellent if they made it thicker, -minus 1 star.No stainless steel screws/anchors for mounting outdoors, -minus 2 stars Just 4 stainless screws for wood & anchors for concrete, would help greatly.I compare it to an electrical outlet that comes with no way to mount it, just unacceptable out in the field, wastes valuable labortime when you have to send someone off the job to shop for mounting screws.

This louver was simple to install. After running the flex duct in the attic, From the outside of the house, I used a hole saw to cut a hole slightly larger than the four inch flex. I reached in the attic and pulled the flex to the outside. After connecting the louver to the flex, everything was shoved back in putting the louver flush to the outside of the house. The provided screws held the louver firmly in place. The plastic seemed a little flimsy, but felt solid after installation.

Purchased as replacement for 10-year old version. Screw holes did not quite align w/those in the original.

Arrived with bird guard. It was relatively easy to install. I wonder why a bird/creature guard is not included in the produc. It would be a LOT better with the bird guard installed when delivered..

Replaced an older cover with this one and it worked out great.

I purchased this to replace the one that blew away during hurricane Matthew. Fits perfectly. Looks great.

Replaced existing one

I find it cheap compared to others I have seen which cost double, but this one is better built, feels solid, I mean, it is plastic, but is it strong enough not to bend easily. I took off one star because product description did not show the back, which had a 4" connector, and I needed it flat to rest on the wall, but I fixed it in 5 mins with the dremmel. Looks good.
