The dog door's strongest selling point is its heavy-duty aluminium frame with a telescoping tunnel and dual magnetic flaps that together deliver a sturdy, energy-conscious solution for dogs up to 220 pounds. Installation is straightforward for anyone comfortable with basic cutting and fastening, and the overall construction leans toward long-term use rather than a light, temporary fix.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminium frame:\u003c\/strong\u003e A rigid aluminium alloy frame provides a durable, rust-resistant opening for exterior walls and holds up better than plastic alternatives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTelescoping tunnel:\u003c\/strong\u003e The Pro 2.0 telescoping tunnel adapts to wall thicknesses from 4 in to 8 in, making the door compatible with a wide range of exterior walls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual magnetic flaps:\u003c\/strong\u003e Two overlapping magnetic flaps create an extra seal to reduce drafts and help keep out wind and light precipitation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSliding lock panels:\u003c\/strong\u003e Two sliding panels lock the opening for full closure and security when the door is not in use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge opening size:\u003c\/strong\u003e With a frame roughly 17 1\/3 in wide by 25 3\/5 in high and a flap of 14 1\/3 in by 25 3\/5 in, the door accommodates very large breeds up to 220 pounds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation guidance:\u003c\/strong\u003e The unit ships with positioning holes and instructions to help simplify cutting the wall and installing the tunnel and frame.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis door is aimed at owners of very large dogs who need a permanent, weather-resistant pass-through in an exterior wall.
