For those that love their patio sliding doors, they sure are going to love this.
Instead of cutting holes in your lovely doors, or doing major construction to cut hole in your wall, take a look at this. This is a quick fitting door that is specially designed to fit in the tracks of your sliding patio doors to still keep the out doors out, but give your pet a door he can come in and out of freely. This is a single panel door with a dual pane pet door making it lighter and more economical than its double paned brethren. The door is spring loaded so that you need absolutely zero tools and only a few minutes in order to get your door installed. The door also features the LEXAN® Ultra-Flex Flap. This flap has three segments with air pockets located in between each allowing an insulated air pocket to form. This unique design cuts down on trapped paws and tails, cannot be chewed, and remains shatter proof. Heavy duty gasket on sides of flap creates a tight seal for additional wind resistance, and extra wide vinyl strip seals the gap between your sliding and stationary panels once the door is in place. This is the perfect alternative to normal door and wall installing pet doors!
