SeaSense Poly Vinyl Keel Roller for Boat Trailers - Heavy Duty Marine-Grade Protection | Perfect for Launching, Loading & Protecting Your Boat Hull

This looks to be a quality keel roller. I bought this one too replace the previous roller that collapsed at the roller "axle". The previous roller was a quality roller too, but these rollers just seem to wear out over time. I'd recommend drilling a hole into one of the far ends of the roller steel axle and instead of installing the top hat, install a SS cotter pin. This makes replacing the roller so much easier
