Extra Large Dog Door for Exterior Doors, Heavy Duty Aluminum Doggy Door for Extreme Weather, Cutout Size 14 1/2''W x 25 1/8''H, Giant Dog Door Up to 220 lbs, Lockable

A heavy-duty aluminum dog door for giant and large breeds with dual flaps, magnetic seal, and a lockable panel. Solid in many installs, but expect a noisy, stiff flap and a serious cut-and-rivet installation.
