The design centers on three overlapping flaps (two magnetic outer flaps and one insulated inner flap) that hold out drafts, rain and insects while still letting a medium pet move freely. Installation fits standard interior or exterior doors or thin walls, and the added closing panel gives control when you need to keep the pet inside.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple flap design:\u003c\/strong\u003e Two magnetic outer flaps plus one insulated inner flap combine to block wind and reduce noise while allowing smooth one-way and two-way passage for a pet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation layer:\u003c\/strong\u003e The middle insulated flap helps shield the home from extreme weather and drafts, improving indoor comfort compared with a single-flap door.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedium flap size:\u003c\/strong\u003e The flap opening measures 13.2in x 7.9in, appropriate for most pets up to 45lb when shoulder height and width are checked against the guide.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoor\/wall fitment:\u003c\/strong\u003e Designed for doors or walls 1.02in to 2.36in thick, making it usable in many interior and exterior installations with a flush fit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosing panel and stickers:\u003c\/strong\u003e A removable closing panel gives control over access, and two pet rescue stickers alert first responders that an animal is inside.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecycled plastic construction:\u003c\/strong\u003e Molded from ocean-recycled plastic for corrosion resistance and environmental benefit, with a promise of replacement flaps if they wear.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis door is best for owners of small to medium dogs and many cats who need a sturdy, weatherproof pet access point for an exterior door or thin wall.
