Situation: The sun room wall is 3 1/2 inches thick. Do I buy the PlexiDor Wall Unit dog door or the PlexiDor Door Unit model?
Answer: The sun room wall is too narrow for our standard wall unit and too wide for our standard door unit kit. However, people have purchased the PlexiDor for sun rooms for years without a special trim kit. The recommendation is to buy the PlexiDor Door Unit and have the sun room company, or installer, frame out the hole for the dog door just like they would for a window. They will then use a U-shaped trim around the exposed wall openings. Then they simply screw the PlexiDor to that trimmed opening.
