The baboni 3-Flap Steel Frame Pet Door handles dogs up to 100 pounds, with a flap opening that’s 10.25 inches wide and 16.25 inches tall. That’s enough space for a Labrador or a large mixed breed to pass through comfortably. The aluminum frame and steel flaps add real durability, especially for dogs that push through with force. The telescoping tunnel adjusts to wall thicknesses between 4.75 and 7.25 inches, so it works in most standard interior and exterior walls without needing a custom build.

Installation is straightforward. The included cut-out template and step-by-step instructions reduce guesswork, and the locking mechanism uses a keyed aluminum lock for security. You can control access without removing the door. The three-flap design helps with insulation, cutting down drafts better than single-flap models. Real-world use: your dog gets independence for potty breaks or playtime, and you don’t have to get up to open the door every hour.

One limitation worth noting: the lock is aluminum, so it’s lighter than steel alternatives. It’s secure enough for daily use, but if you’re in a high-traffic area with very strong dogs, the lock mechanism may wear faster than an all-steel version. For most large breeds and standard home use, this is a solid, no-fuss pet door that balances size, strength, and ease of installation.
