This is a set of the INA520 roof carrier (140cm) and the IOP51 rail kit. It was only used for about a month and then disassembled and stored in a box. For the price, I think it has a great sense of weight, rigidity, and durability that doesn't look cheap. The RVBOX got scratched, and the carrier itself has some scratches. (See images) It's very rugged and cool, but I always need a kayak carrier on my roof, so it doesn't fit my needs. I'm selling it to someone who needs it. - Model: INA520 140cm / IOP51 - Material: Steel - Accessories: Hex wrench The first three images are from the Carmate website. The rest are pictures of the actual product. Please check the images. There may be some rust on the bolts, but since it was used minimally, it's in good condition with only a few scratches. I think it will be shipped in two large boxes. Thank you. Thank you for looking.
