RV-INNO ski and snowboard carrier (set of 2). Used a few times in the beginning and then stored for about 20 years. There are no accessories other than what is shown in the photos. There is no security key. The boards snap in, so it should be fine, but if you are concerned, you may want to secure them with a strap or something. ・Brand: RV-INNO ・Model number: IN-647 Thank you.
