Use it when your dog or your door doesn't fit one of the five stock sizes on the standard door mount.The aluminum frame and clear vinyl flap are rated from 0°F to 120°F. Available in white and black. Flap widths run from 4" to 18" and heights from 5" to 40", chosen from discrete bands rather than typed-in measurements. A locking cover ships with each unit.Before ordering, measure your dog's shoulder width and chest height, then add roughly an inch of clearance on each axis to pick the right flap range. Also confirm the door itself can fit the frame: the cutout sits between the top rail and bottom rail of the door, with some margin. If a stock size works, the standard door mount is cheaper and ships sooner.Made in the USA and backed by a 3-year warranty. Custom orders add a few extra days of lead time.
