Matched to vinyl slider tracks: Vinyl frame seats cleanly in vinyl sliding-glass-door tracks 1.25" wide or wider Five flap sizes: Small, medium, large, XL, and XXL, sized for dogs from terriers up through large breeds Track heights 74" to 101.5": Stock height variants in 3.5" bands, plus a custom-height option White frame only: Designed to blend with white vinyl sliding door frames Made in USA, locking cover included: Built domestically and backed by a 3-year warranty The Liberty Pet Door Vinyl Patio Panel is a vinyl-framed insert for sliding glass doors with vinyl tracks. The vinyl frame matches the look of a standard white vinyl slider and tends to seat better in vinyl tracks than aluminum panels do. Available in white only, with five flap sizes (small, medium, large, XL, XXL). Stock height variants run from 74" to 101.5" in 3.5" bands, with a custom-height option for outliers. A locking cover ships with every unit. Removes cleanly when you move, which makes it a fit for rentals. Before ordering, measure the inside height of your sliding glass door track and confirm the track width is at least 1.25". If your slider has an aluminum frame instead of vinyl, the aluminum patio panel is the right match. Pick flap size by your largest pet's shoulder width and chest height. Made in the USA and backed by a 3-year warranty. Install is an easy DIY job that takes most owners under an hour.
