VEVOR Pet Door, Medium, with Three Magnetic Flaps and Metal Frame, Strong and Weatherproof Dog Door for Interior and Exterior Doors, Easy to Install, Easy In-and-Out Access for Doggies, White

Medium Dog Door with Q235 Steel Frame and 1.0mm Thickness for Lasting Daily Durability 

The VEVOR medium dog door, made from Q235 steel and featuring a 1.0 mm frame thickness, provides a durable frame for everyday indoor and outdoor use. Frequent daily use places repeated stress on the frame and flap assembly. The Q235 steel frame helps maintain alignment during regular operation. 

The door is a manageable size for one person to install into a pre-cut or existing door opening. It weighs 7.2 pounds (3.25 kg) and measures 16.6 by 11.9 by 3.0 inches. Standard white interior and exterior door finishes complement the white powder-coated finish on the steel frame.

Triple Magnetic Flap System for a Flush, Draft-Resistant Closure After Every Pass 

The three-panel magnetic flap has magnets built into the edges where the three flexible panels meet. These magnets pull the flap back into a closed, flush position every time a pet goes through. The three magnetic flaps create multiple sealing layers that help reduce drafts and improve closure. This creates a composite seal that sits flat against the frame opening, rather than leaving a gap at the flap center or edges, as a single-panel design can when the magnetic closing force is not strong enough to overcome the resistance of a stiff or slightly bent flap.

During inclement weather, the magnetic closure also makes it harder for wind to open the flap from outside the door. The magnetic closure helps keep the flaps closed during normal outdoor conditions. This wind resistance keeps the flap closed when the weather is mild, so the owner does not have to use the locking panel every time the wind picks up.

8.25×12.25 in Flap Opening for Comfortable Medium Dog Breed Access 

The flap opening is 8.25 inches wide and 12.25 inches tall, a natural, upright size for medium-sized dog breeds to pass through without having to crouch, twist, or struggle in a tight fit that would make them less likely to use the door on their own. The width fits the shoulder span of medium-sized dogs such as Spaniels, Beagles, Border Collies, and others with a similar build. The height, on the other hand, gives the dog's back enough room to clear the top flap edge without touching it during regular passage.

The 65 HA flap rigidity rating provides a flap stiffness level that is firm enough to reliably return to the closed position after each pass and to resist minor wind pressure from the outside, yet flexible enough for a medium-sized dog to push open from either direction without much force. The flap balances flexibility with enough rigidity to return to the closed position after use. 

Compatible with 1–2 in. Door Thickness for Interior and Exterior Door Installation 

It fits door panels between 1 1/16 in. and 2 in. (2.7–5.08 cm) thick. This includes all standard thicknesses for hollow-core and solid-core residential doors on the inside, as well as the thicker exterior doors used in insulated entry and garden doors. This range lets you install the same medium dog door on a bedroom or utility room door, a standard back door on the outside, and a yard-side gate door, all without buying a separate unit or extra extension tunnel sections for each door type.

Installation works with both interior and exterior door positions—the flap and magnetic closure work well in either direction, and the steel frame and white powder-coat finish are suitable for indoor and outdoor installation. For homes where the owner wants to let the dog in through both an inside door to a utility room and an outside door to the yard, the same medium dog door specification works for both locations.

Medium Dog Door with Locking Slide Panel for Controlled Pet Access When Needed 

The medium dog door has a locking slide panel that fits into the frame and completely blocks the flap opening when pet access needs to be limited, like at night, when guests who do not like pets are there, when the dog needs to stay inside for health or training reasons, or when the house is empty and gate security is important. The solid locking panel blocks flap movement from either side when installed. 

You do not need any tools to engage or disengage the locking mechanism. This lets the owner quickly allow and stop pet access as needed during a normal day. When pet owners want to give their dogs independent access to the door during the day while also ensuring the door is safe and draft-free at night, the locking slide panel can do both within the same installed door unit, without requiring any changes to the door or door frame.

All Hardware Included for Fast, Tool-Simple DIY Installation in Minutes 

Attaching the dog door to a pre-cut door opening is easy with the hardware that comes in the box. It has all the screws, fasteners, and frame parts you need. The steps for installation are to cut a hole in the door panel that is the right size for the flap opening, place one half of the inner frame on each side of the door, line up the two halves through the thickness of the door, and use the fasteners that come with the frame to clamp it onto the door panel.

Installation can be completed using common household tools such as a jigsaw and screwdriver. Most homeowners can complete the installation using common household tools. The user manual that comes with the kit walks you through the whole installation process, from marking and cutting to putting together the frame. Once installed, the pet door is ready for normal use.
