This is a dedicated attachment for installing the OGK roof mini front rain cover. I purchased this from someone who had mistakenly bought the wrong attachment, but I also made the same mistake, so I am selling it unused. This product is the type on the right in the third photo (for the current Panasonic Gyutto Crewm). I use a model of Panasonic Gyutto Crewm from a generation ago. Please note that this is very confusing, as the middle OGK genuine product in the third photo, as well as the same shape Panasonic genuine products manufactured by OGK (NCD510S/NCD511S/NCD512S), are compatible child seats. *Please use my notes as a reference only, and confirm the compatibility yourself based on the shape of the attachment, etc. *Only the part of the box with the installation instructions will be cut out and shipped. Thank you.
