Baboni 3-Flaps Pet Door for Interior and Exterior Doors - Large

Our review of the Baboni 3-Flaps Pet Door finds it best suited for owners of large dogs and heavyset pets who need a durable, insulated passage between indoors and out. The single biggest reason to consider this model is its combination of a metal frame and a three-layer flap system that prioritizes weather resistance and security, while the telescoping tunnel fits thicker doors so installation is possible on most interior and exterior doors.

Key Features

• Freedom and independence: Pets up to 100 lb can use the 10 1/4 in by 16 1/4 in opening to come and go for potty breaks or play without owner assistance.
• Telescoping tunnel: The tunnel expands to accommodate door thickness from 1 3/8 in to 1 31/32 in, simplifying fitting to varied door builds.
• Durable metal frame: A steel and aluminum alloy frame with laser welding gives a rigid, secure perimeter that holds up to everyday use.
• Three-flap energy saving: Two vinyl flaps with magnetic closure plus an insulated middle flap help reduce drafts and improve thermal insulation.
• Included hardware and template: A cut-out template and step-by-step instructions are supplied to make the install straightforward for most DIYers.

Who It's For

The Baboni 3-Flaps Pet Door is ideal for owners of larger dogs or sturdy mixed-breed pets up to 100 lb who want a long-lasting, insulated entryway in an interior or exterior door. It suits households in climates with cold or windy seasons where the extra insulation from a three-flap design will reduce drafts and heat loss.

It is less suitable for very small pets that need a smaller flap, or for owners who require a perfectly rigid, maintenance-free vinyl flap in blazing sun; some users note vinyl components can shrink or wear over time and replacement parts may be needed if damaged.

Pros & Cons

Pros

• Sturdy metal frame and welded construction provide a secure, long-lasting opening.
• Three-flap system with an insulated middle layer improves air insulation and weatherproofing.

• Generous flap opening fits most large dogs and heavy cats up to 100 lb.

Cons

• Vinyl flaps may shrink in strong sun and some customers reported flap damage within a month of heavy use.
• Not intended for extremely thin doors outside the stated thickness range without additional modification.
