Daiichi Seiko Super Uketaro 240 Mounting width is approximately 240mm. The condition is quite good. However, there are 4 holes of about 5mm in the gunwale clamp part, so please check photo 5. This is in a place and to an extent that does not interfere with use. Each part operates well. The screws also turn smoothly. Can be used without any problems. Please refrain from purchasing if you are looking for a perfect item. Rod holder Rod rest Boat fishing Raft fishing Sea fishing pond Ukejirou Uketaro 130
