It is the part the flap actually clips into, and it sits between the flap and the main aluminum frame.Available in four sizes (small, medium, large, extra-large) and two mount-type variants: one for Door and Wall Mounts, and one for Slider and Window Panels (including the white sash version). The kit ships with the bracketry needed to mount it.Before ordering, confirm the size and mount type of your existing Liberty pet door. Most owners replacing the adapter are also replacing the flap itself, since both wear together. The Cat Flap and XXL sizes are not part of this adapter line.Made in the USA. Easy DIY swap.
