The Manutec BDA062 is a 4.5″ cotton reel keel roller kit designed for trailer owners who need gentle yet sturdy keel support for fiberglass hulls.
This all-in-one kit includes a soft-touch cotton roller, galvanised steel bracket, and spindle—ready for quick installation.
With its 17mm bore perfectly fitting 16mm shafts, the roller is made from UV-stable material offering high protection without scuffing or scratching.

The hot-dip galvanised bracket ensures resistance against corrosion, while the included spindle makes this kit a simple bolt-on solution with no extra parts needed.
