Dog Door 3-Flap Magnetic Pet Door for Interior & Exterior Doors or Wall – Heavy Duty Insulated Doggie Door with Closing Panel, Medium & Large, Fits Dogs 45–100 lbs, White & Black

Dog Door – 3-Flap Magnetic Pet Door for Doors & Walls

Give your dog the freedom to come and go as they please with this heavy-duty 3-flap magnetic pet door. Designed for installation in interior doors, exterior doors, or walls, it features a triple-flap insulation system and dual magnetic closure to keep drafts, rain, and pests out while letting your pet move freely.

Triple-Flap Insulation System

Three overlapping flaps create a superior insulation barrier, blocking cold air, wind, and moisture from entering your home. Far more effective than single-flap designs, keeping your home comfortable year-round.

Dual Magnetic Closure

Two powerful magnets ensure the flaps close securely after each use, preventing drafts and maintaining your home’s energy efficiency. The magnetic seal is strong enough to resist wind but easy enough for pets to push through.

Closing Panel Included

The included closing panel lets you lock the door when needed — ideal for nighttime security, travel, or keeping pets in a specific area of the home.

Heavy-Duty Outdoor-Grade Construction

Built from reinforced heavy-duty polymer with a thick, impact-resistant frame. Designed to withstand weather extremes, daily use, and the wear and tear of large, active dogs.

Versatile Installation

Compatible with interior doors, exterior doors, and walls. Suitable for dogs weighing between 45 and 100 lbs.
