Aluminum Large Dog Door for Exterior Door - Strong, Locking Pet Door

In this review the MAVRICPOWER Aluminum Large Dog Door is examined for owners who need a rugged, weather-resistant pet passage for exterior doors. The bottom line: this door is best for medium to large dogs up to about 80lbs and for homeowners who want a secure, insulated opening that fits common door thicknesses; its single biggest selling point is the combination of a sturdy aluminum frame with double locking panels that improve security and reduce drafts. The review focuses on real-world installation, durability, and how the magnetic flaps perform in everyday use.

Key Features

• Flexible Size: The expanding tunnel adjusts to fit doors from 1 3/8 in to 2 1/8 in thick, letting it work on paneled, wood, PVC and metal exterior doors.
• Large Opening: The flap opening measures 11 1/8 in by 16 1/4 in, providing ample clearance for many large breeds up to 80lbs to enter and exit comfortably.
• Strong Construction: The rugged aluminum frame and tunnel resist chewing and wear better than thin plastic options, making it suitable for active dogs.
• Two Magnetic Flaps: Magnetic seals on the flaps help the door reset quickly and maintain a tighter closure to keep out drafts and insects.
• Double Locking Panels: Two sliding lock panels allow owners to restrict access or reduce heat transfer in rough weather for better climate control.
• Installation Kit Included: A cutting template, step-by-step guide and hardware are supplied, and rivets are recommended for hollow doors for extra security.

Who It's For

This dog door suits owners of larger dogs up to around 80lbs who need a durable exterior door solution that resists damage and limits drafts. It is especially relevant for people with paneled, wood, PVC or metal doors within the stated thickness range who want a lockable, insulated option with a generous flap size.

It may not be ideal for owners of very small dogs or apartments where cutting an exterior door is not allowed, and shoppers who require electronic selective entry or full weatherproofing beyond magnetic seals should look at other specialized systems.
