PATIO DOG DOOR INSERTS

The smartest way to add a dog door to your sliding glass patio door.

Adding a pet door to a sliding glass door used to mean cutting glass or compromising security. High Tech Pet's patio panel inserts slide right into your existing sliding door track — no cutting, no contractor, no hassle. In minutes, your pet has freedom. Your home stays secure.

Our line spans four distinct products: from the industry-defining Power Pet Roll-Up with full Wi-Fi app control, to the DuraFlex magnetic-seal insert built to outlast everything else on the market. Every panel features heavy-gauge aluminum construction, dual-pane Low-E glass, and a universal lock that fits most sliding glass door frames.

Any Dog, Any Size

Sizes for small breeds through dogs up to 200 lbs.

Minutes to Install

No glass cutting or contractors. Just slide the panel into your existing track.

Universal Security Lock

Works with most sliding glass door frames and installs on either side.

Dual-Pane Low-E Glass

Energy-efficient glass helps keep your home comfortable year-round.

How to choose the right patio dog door

The most important question is whether you want automatic or manual access. Automatic doors like the Power Pet Roll-Up and Power Pet Classic use a pet collar sensor to open and close the flap — keeping strays and intruders out while letting only your pet through. Manual doors like Armor Flex and DuraFlex use a flexible flap your pet pushes open themselves.

Next, measure your sliding glass door frame height. Most standard patio doors are 75"–80.25" — our "Regular" height panels. Taller doors (92.75"–96") need our "Tall" height models. All panels are available in multiple sizes to match your dog's shoulder height and weight.

Finally, consider the weather where you live. If you're in a windy or cold climate, the DuraFlex rare earth magnetic seal is the most weathertight pet door panel ever made.

COMMON QUESTIONS

Patio Mount Dog Door FAQs

Answers to the most common questions about patio pet door inserts for sliding glass doors.

Will a patio pet door insert fit my sliding glass door?

High Tech Pet patio panels fit most standard sliding glass door tracks. Regular height panels fit door openings of 75"–80.25" tall; Tall height panels fit 92.75"–96". Measure the interior height of your door track before ordering. If you're unsure, our team at 1-800-255-1279 can help you confirm fit.

Do I need to cut the glass or modify my patio door?

No. All High Tech Pet patio panels slide into your existing door track alongside your current sliding glass panel — no glass cutting, no structural modification, and no contractor required. Installation typically takes 20–30 minutes.

What's the difference between automatic and manual patio pet doors?

Automatic doors (Power Pet Roll-Up and Power Pet Classic) use an electronic sensor in your pet's collar to detect their approach and open the flap automatically. This keeps strays and other animals out. Manual doors (Armor Flex and DuraFlex) use a flexible flap your pet pushes through themselves — simpler, no electronics required, and extremely durable.

Is my home secure with a patio pet door installed?

Yes. Every High Tech Pet patio panel includes a universal security lock that mates to your existing door frame, plus a security lockout panel you can use when you're away. Automatic doors add a second layer: only a pet wearing the paired collar can activate the door. The Roll-Up flap itself is constructed from rigid interlocking polycarbonate — it cannot be pushed open by hand.

What size do I need for my dog?

Measure your dog's shoulder height (the top of the back, not the head). The flap opening should be at least 1"–2" taller than their shoulder height. We offer sizes for dogs from small breeds up to 200 lbs. Our product pages include detailed size charts — or call us and we'll help you choose.

Does a patio pet door affect my home's energy efficiency?

All High Tech Pet patio panels feature dual-pane, Low-E glass in the panel itself — the same energy-efficient glass used in quality replacement windows. The Dura Flex in particular is designed for maximum weatherproofing, with a rare earth magnetic flap seal tested to remain airtight in winds up to 50 mph.
