This is a set of the now discontinued Canoe Roller in-410 and Boat Roller Pro in-420 ratchets. The Canoe Roller originally had a C-ring to insert and secure it to the main body, but it is missing. It tends to come apart when attaching it to the carrier, so please be careful about that. Otherwise, it can be used without any problems. There may be other missing parts. Please judge from the images. The ratchet mechanism should be fine. You will need to prepare belts separately. ※Please ask if you have any questions.
