Rated 3.6 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by good purchase, product is clean, no defects, no complaints, delivered on time as promised very good purchase, fulfilled all expectations. highly recommend this product. November 3, 2015
Rated 3.0 out of 5.0 by OK, could be better. The product arrived slightly bent and both lengths that I bought had slight dings in the sides of the aluminum. So boxing for shipping 6' could have been done better. The slight bend straightened out. Getting the gasket on was very hard--no instrucs specific to that---so I think, though the gasket is on, it is not ultimately seated right. The gasket, in any case, sticks up too high. March 31, 2015
Rated 1.0 out of 5.0 by CAUTION!!! If you have aluminum french doors The picture of the threshold plate gives a misleading look at it. It is more flat then how you see it in the picture to make it a better quality threshold plate. I was cautious about it and was almost not even going to give it an option but when I got to the store it looked perfect but................ I have to give you the issue I had with my double French doors. My mothers house was built in 1995 and have had a problem with water getting in. This threshold was an ideal fix for the problem BUT when I installed did not get to the bottom of the door. It was off about 1/8". So I cut a board 3/8" of an inch thick so the rubber on the threshold would sit at the bottom of the door and overall seal it. After I closed the door and then opened it back up IT PULLED THE ALUMINUM DOOR SKIN AWAY FROM THE FRENCH DOOR. These doors have a an aluminum skin with stirefoam in the top and bottom of the door with the glass in the middle. At the extreme bottom and top of the door is a small wood filler piece and also the sides of the door. Then it has stirefoam in between the glass of the door. Now it says up to 3/4 of an inch and if there's a smaller gap under the door you have the possibility of the threshold doing the same thing to your doors. Now I was only giving it about 1/4 of an inch for the rubber to meet the bottom of the door and this is my outcome. You have to be almost exact for it to work and probably if you have a solid wood French door it would work perfectly. The other two reviews had a 5 star rating and I wish I had a 5 star outcome. SO BE AWARE It was such a disappointment. May 9, 2014
