Eillion 3-Flap Large Dog Door for Sliding Glass Doors – Adjustable 75-7/8 to 81 in

Discover the Eillion 3-Flap Large Dog Door for Sliding Glass Doors, a thoughtful solution designed to fit tall sliding doors while keeping your home comfortable. Built with a triple-flap system and double magnetic closures, it helps minimize drafts and wind while preserving interior climate. The flap is semi-transparent for better visibility, and a safety lock lets you control when your pet can go outside. The opening direction is fixed by installation: left-side mounting opens inward, while right-side mounting opens outward. This model is not adjustable for opening direction, and installation requires drilling into the door frame.
