Don't get up! Your dog or cat can let himself in and out of your home with this All-Weather Pet Door. What makes this pet door unique? It's the all weather thermal insulated construction with exterior weather slide and interior lockout slide. The innovative double vinyl flap design creates an energy efficient air pocket for maximum insulation, and a draft restrictor made of nylon fur also saves energy. This pet door has an inner telescoping frame that adapts to doors 1 1/4" to 1 3/4" thick with no inner frame needed. This all weather pet door is made from energy-efficient structural foam molded plastic. An optional wall kit allows you to install your pet door in walls from 4 3/4" - 7 1/4' thickness, and comes complete with hardware and detailed instructions.
