We developed a sturdy thermoplastic telescoping frame; flexible vinyl flap; a floating sill to insure good closure; and a strong molded ABS lock-out slide to restrict the pets movements when necessary. Then we made it 4 sizes for pets up to 120 pounds. And with a tamper proof mounting system and easy installation, its the most economical pet door in the industry.
