ITEM SPECIFICS
The BDA016 is a compact and reliable keel roller and bracket combo, ideal for small boat trailers and tight installations.
It includes a 4.5″ blue UV-stable polypropylene roller with a 17mm bore, designed to fit 16mm spindles, along with a hot-dip galvanized standard bracket.
With a narrow 114mm roller width and 50x50mm clamp-on stem adjusters, this kit is perfect for compact trailers where space-saving and weight distribution are essential.
The non-marking poly roller is gentle on alloy and fiberglass hulls, while the galvanized bracket resists corrosion for long-term use.
Additional clamp sizes are available if your trailer frame dimensions vary.
