The design centers on two magnetic flaps plus an insulated middle flap, which together provide noticeably better protection from drafts, rain and bugs than a single-flap unit. Installation fits typical doors or thin walls and the Medium size accommodates pets up to 45lb, making it a practical upgrade when air protection and a closing panel matter.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eThree-flap system:\u003c\/strong\u003e Two magnetic flaps plus one insulated flap give improved windproof, waterproof and soundproof performance compared with single-flap doors.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eInsulation layer:\u003c\/strong\u003e The middle insulated flap helps reduce drafts and keeps extreme weather from entering the home.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eMedium opening size:\u003c\/strong\u003e Flap opening measures 13.2in x 7.9in, suitable for most pets up to 45lb when you measure shoulder width and height first.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eDoor and wall fitment:\u003c\/strong\u003e Designed to install in doors or walls with a thickness of 1.02in to 2.36in, offering flexible placement in many homes.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eClosing panel and safety stickers:\u003c\/strong\u003e A manual closing panel lets you control access, and two pet rescue stickers alert responders in an emergency.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eRecycled plastic construction:\u003c\/strong\u003e Made from recycled ocean plastic that resists rust and reduces environmental waste.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis pet door is aimed at owners of small to medium dogs and cats who need a sturdier, more weather-resistant option than a single-flap unit.
