Firstly this screen is for Lippert doors only. Do not follow Amazon's sizing instructions. Find the sticker on the inside of your Lippert door that says your door size and order that size. My Lippert RV door is 30 inches. I ordered 30 inch and it fits perfectly. I almost ordered a 28 inch monitor by following the instructions in the video on Revain. I went back and read the most helpful reviews. So I'm just adding one more verification review to give credibility to the other reviews here. The installation instructions are not very clear. I figured it out pretty quickly, just using common sense and drawing conclusions from the instructions. We have small dogs. For a large dog, you may need a more durable device.
