The G-SDDSLC is the Catwalk® Maxi pet door — for all cats, including large breeds such as Maine Coons, and small dogs up to about 300mm at the shoulder, such as Chihuahuas, Toy Poodles, Maltese and Yorkshire Terriers. The usable opening is 187mm wide × 190mm high (the flap panel is 203mm high; about 13mm sits in the hinge). Before ordering, measure your pet standing: width at the widest point + 25mm must fit inside 187mm, and body depth (top of shoulders to bottom of chest) + 25mm inside 190mm. Fit the door with the bottom of the opening level with your pet’s belly. Bigger dog? See the G-IDDSLC Intermediate dog door, or use our Pet Door Selector for a personalised recommendation.

The G-SDDSLC frame has a 9.22mm projection depth on both the inner and outer face of the glass. This minimal projection depth keeps the door as flush and low-profile as possible on both sides of your window or sliding door.
