Give your dog the freedom to explore while keeping your home secure and draught-free with the Pet One Polycarbonate Insulated Dog Door. Specially engineered for versatility, this high-impact door fits seamlessly into security screen doors (mesh and perforated steel), single-glazed glass panels, and glass sliding doors (3 mm to 15 mm thickness, with a minimum 17 mm sliding clearance). Constructed from 100% UV-stabilized polycarbonate, the flap is virtually unbreakable and designed to withstand tough daily use without yellowing or cracking in the sun.
Featuring a 2-way manual locking mechanism along with two additional security latches, you can easily control your pet's access while adding extra strength against uninvited entry. The self-closing magnetic flap is fitted with brush weather seals to automatically close behind your pet, keeping unwanted draughts, wind, and rain outside where they belong.
Key Features:
Crafted from high-impact, 100% UV-stabilized polycarbonate for extreme durability
2-way manual locking system (In/Out, Locked) to manage your pet's access
2 extra security latches provide reinforced locking strength
Self-closing flap with integrated brush weather seals stops cold draughts and weather
Versatile installation designed for screen doors and single-glazed glass panels (3 mm – 15 mm thickness)
Fits sliding doors with a minimum clearance requirement of 17 mm; suitable for pre-cut safety glass
Dogs up to 25 kg (depending on selected door size) needing seamless indoor and outdoor access.
Pro Tip: When installing into glass, always consult a professional glazier to ensure safety glass is pre-cut correctly prior to toughening, as toughened safety glass cannot be cut after manufacturing!
