You've got the roller, you've got the axle, and now you need a clamp that actually grips your specific hull setup without slipping. This 50×25mm compression clamp takes an 18mm square stem and locks your roller in place. No guessing whether it'll hold through the next tide. You bolt it on, tighten it, done. Part of a range that covers a spread of boat configurations, so you're not left with a clearance gap or an over-tight squeeze
