Measure your pet's shoulder height — the highest point on their back, not their head — and add 1–2 inches. That's your minimum flap height. High Tech Pet wall mount dog doors are available in medium (up to 30 lbs), large (up to 100 lbs), and XL (up to 130 lbs). If you're between sizes, go up. Call 1-800-255-1279 and our team will help you find the right fit.

For maximum security and smart features, the Power Pet Roll-Up wall mount is the most advanced option — motorized, Wi-Fi enabled, collar activated, and airtight. For a proven automatic wall mount, the Power Pet Classic is a top-selling choice. For a no-power manual wall mount, the Armor Flex and DuraFlex offer the best weather sealing. All include an aluminum tunnel and are available in medium, large, and XL sizes.

Patio inserts are the easiest installation of all three types — they slide directly into your existing sliding glass door track with no cutting, no drilling, and no contractor required. Door mount takes about 20 minutes with basic tools and requires cutting through an existing door. Wall mount requires cutting through your wall and filling it with the included aluminum tunnel, typically a 1–2 hour project.

High Tech Pet automatic doors are collar activated. Each door comes with an ultrasonic collar — simply turn on the door and put the collar on your dog or cat. The door's sensors detect when a pet wearing the collar approaches and opens automatically. No training or programming needed. Pets without a collar cannot open the door, keeping strays and wildlife out. You can also control the door via Wi-Fi app (on Wi-Fi models) to set schedules, lock the door, and monitor activity.

Both are premium manual wall mount doors with heavy-gauge aluminum construction, rare-earth magnet seals, and aluminum tunnels included. The DuraFlex specifically uses a rare earth point-magnet system along the entire flap perimeter for a tighter, more weatherproof seal — tested airtight in winds up to 50 mph. If you live in a cold, windy, or wet climate, the DuraFlex is the stronger choice. For milder climates, both perform exceptionally well.

Yes. High Tech Pet wall mount doors install in standard wood-framed walls up to 7⅜" thick using the included aluminum tunnel. Thicker walls can be accommodated by adding extension tunnels. For concrete, brick, or stucco walls, additional framing may be required. Call 1-800-255-1279 and our team will help you plan the installation for your specific wall type.
