Bests & Worsts Reviews from Amazon

I ordered this door to install myself. The installation requires some knowledge of carpentry as you have to cut through the wall. The door itself is perfect and easy to install once you cut the dimensions into the wall. My 2 dogs that previously rang a bell hanging on a rope to be let out, learned very quickly to use it. The double flap keeps the cold air out even in march in new jersey. I would not recommend this sized for a large dog such as a golden retriever or a dog of similar size. get a taller wider door for such a pet. My dogs are 25 pounds and 19 pounds and it is perfect, a beagle and a jack russel terrier. It comes with a solid slide in stop if you choose to lock the opening either from the outside or inside. I recommend this product. after much research this was the best value for money. Here is a little help if you are going to do it yourself. A-It fits between 2 wall studs that are 16inches apart. B-use a stud finder to determine where the studs are inside the wall. C-make sure that there are no wires or pipes in that area. you can cut a small hole and check. D-Make sure that the bottom of your hole is high enough above the grass, ground or deck so that water or rain will not come in when it accumulates in the area. E-Mark the hole to be cut with the cut out paper they provide. F- Cut the sheet rock with a small sheetrock saw make the cut slightly larger that the paper cut out so it will fit easily. G-Remove the sheetrock and the insulation inside the wall. wear a long sleeve shirt and gloves for this part. H-Drill holes on the exterior wall plywood corners fron the inside of your house. I-Connect the holes outside with a marker, pencil. J-Cut the opening with an electic saw and remove it. K-Install one side of the doggie door and have someone help on the inside by fitting the other side. Once it is flush with the ouside wall screw it in L- do the same inside. M- The flaps have a magnetic catch in the bottom to keep them closed once the pet walks through it. Good luck with the project, I hope this helps, or at least will help you determine if you can do it, or want to a handyman to do it.
