Key Features

• Adjustable frame: The frame fits window widths from 33 to 38 in so it adapts to different sash openings without major modification.
• Minimum window height requirement: Requires at least 20-3/8 in of sash height, which ensures the panel sits securely and safely in most standard sash windows.
• Large clear flap: The 10-1/2 x 15 in clear vinyl flap gives pets a full, visible path and is made of non-toxic material for safety and reassurance.

• White patio-style frame: The elegantly white patio panel frame with clear tempered safety glass blends into home decor and keeps the installation looking tidy.

Who It's For

The Ideal Pet Products Aluminum Sash Window Pet Door is best for owners of medium to large dogs and similarly sized pets, roughly in the 36 to 90 pound range, who want a tidy, window-mounted option rather than a wall or door cut. It is also a good choice for people who prefer a product that installs quickly and looks like a finished window panel.

It is not suitable for very small pets under the suggested weight range or for homes where sash height is under 20-3/8 in. If a permanent wall installation or an ultra-heavy-duty flap is required, shoppers should consider wall-mounted or reinforced options instead.
