Natural Wood Cannon-Style Vise Total Length: 200mm Height: 145mm Base Mounting Dimension: MAX approx. 40mm Insertion Diameter: 12.8mm Includes storage bag Material is unknown, but it's a somewhat small vise. Due to its holding power, it can also be used for long rod stands. With its unique design, using it in combination with regular items will expand your options. I used this with a bamboo rod stand and bamboo rod for a relaxing fishing experience. For those looking for one, how about it?
