Super Lark and Shakuri Lark are sold as a set. Since there is only one clamp and DX support, please switch them according to your needs, such as the mounting position on the boat. As for the Super Lark, it can be attached vertically and horizontally as shown in the image. There are some scratches due to normal use, but there are no problems in using it. You can still use it. Please consider this item as a used product. Feel free to comment (^-^)
