VEVOR Pet Door, X-Large, 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

XL Dog Door for Door Built for Large Breeds with 13.6×23.6 in Passage Opening 

The VEVOR XL dog door for door has a flap opening measuring 13.625 inches wide and 23.625 inches tall (34.61 × 60 cm). This is big enough for large dog breeds and similarly sized dogs to go through naturally, without excessive crouching or squeezing. The width and height measurements create a passageway that fits the shoulder width and height of large breeds. The design provides comfortable access for many large dog breeds. 

 It weighs 15.4 pounds (7 kg) and measures 28.0 by 17.2 by 3.0 inches. This size is suitable for large working and companion breeds. When a big dog walks normally and pushes through the flap, the extra frame mass keeps it straight even with greater contact forces.

70 HA Flap Rigidity for Strong Closure Resistance and Self-Return After Every Pass 

There is a 70 HA hardness rating on all three flap panels. This rigidity is important for two reasons that are unique to the XL format. First, the taller 23.625 in flap height requires a stiffer panel material to resist the greater gravitational moment acting on the lower portion when partially open. A softer flap at this height would sag at the bottom edge instead of returning to a closed position smoothly after each pass. The 70 HA flap balances rigidity and flexibility, helping the flap return to its closed position after pets pass through. 

Second, the higher rigidity makes the door less likely to open in the wind. This is important for installations outside, where the large flap area gives wind pressure more surface to act on. The 70 HA stiffness works with the magnetic closure force to keep wind from getting through the flap face when it is windy outside.

Triple Magnetic Flap Panel for Air-Tight Seal Across the Full Flap Height 

Three magnetic flaps create multiple sealing layers that help improve closure across the full flap height. This ensures the flap seals flat against the frame from top to bottom simultaneously, without any parts in the middle or bottom bending outward, which would occur if a single magnetic pull were not strong enough to keep the whole panel flat.

The flush seal closes the surrounding flap gap, preventing cold air, wind-driven rain, and bugs from getting in when the door is closed and not in use. In cases where this XL dog door for door is the main way to get from a warm room to the outside, the quality of the seal directly affects how comfortable it is inside during cold weather and at night.

Q235 Steel Frame at 1.0mm for Structural Durability Under Heavy Daily Use 

Fabricated from Q235 carbon steel with a wall thickness of 1.0 mm, the frame, tunnel, and retaining parts are strong enough to withstand daily use by large, active dogs. Frame contact points at hinge places, tunnel edges, and magnetic retaining surfaces all experience repeated mechanical loading. Q235 steel helps maintain these dimensions over years of use.

The white powder-coated finish protects against corrosion on external doors and complements white painted wood or UPVC door panels, which are popular in residential exterior installations. The powder coat prevents the frame edges from chipping when dogs rub against them repeatedly during daily use, as long as the installation is in place.

XL Dog Door for Door with Locking Slide Panel for Night-Time and Absence Security 

The frame has a locking slide panel that completely closes the flap opening when it is engaged. This keeps people on either side from reaching the magnetic flaps or the tunnel section. It only takes seconds, and no tools are needed to engage the lock, which turns the active pet access point into a secured panel that keeps pets from leaving during the night, when the owner is not home, or when controlling pet movement is temporarily needed for safety or behavior management.

The locking slide panel completely blocks the flap opening when pet access needs to be restricted. When the house is empty, the locking slide panel blocks this access path completely. This helps improve security when the door is not in use. 

Fits 1–2 in Door Thickness with Full Hardware Kit for Straightforward Owner Installation 

This XL dog door for door fits door panel thicknesses between 1 1/16 in. and 2 in. (2.7–5.08 cm), making it suitable for many common residential interior and exterior doors. All the hardware needed for a full installation is included, including frame fasteners, inner and outer frame halves, and locking slide components. This means that installation can be completed with common household tools. 

Follow the steps in the user manual to install it: measure the opening, cut the opening to fit the door, insert and line up the inner and outer frame halves through the door thickness, and then clamp the frame firmly by fastening them together. Once installed, the pet door is ready for normal use.
