Thank you for viewing! This is a THULE magnetic type snowboard carrier. I DIYed it by attaching a snowboard adapter to a genuine ski carrier using strong adhesive. Installation is easy: just place it on the roof of your car (the top) and it sticks on (see the last image). Removal is also easy: just gently pull the removal strap (see image 12). I've lost one of the rubber bands, so there are only three. I used a bicycle basket band as a substitute, but you can probably just tie it with a regular string. It's still perfectly usable, but I no longer need it since I bought a minivan, so I'm selling it at a low price to someone who will use it. Please refrain from purchasing if you are overly concerned about minor details. The price is set arbitrarily, so feel free to make an offer if you have a desired price. I'm decluttering, so I have other items for sale as well. Combined shipping with other items is possible. Please feel free to ask! I'm also planning to list this on other sites and at a garage sale, so it may be removed suddenly. I can also hold it for you, so please contact me as soon as possible. I do not have any pets, and I am a non-smoker.
