In stock
The Manutec BDA059 is a heavy-duty 12″ black rubber keel roller kit designed for serious support and stability on boat trailers.
With a wide 300mm roller and dual galvanised bracket, this setup is ideal for larger fiberglass boats needing reliable keel alignment and impact absorption.
The roller is made from durable 85 DURO black rubber, which provides excellent shock absorption and prevents hull damage during launch and retrieval.
The 26mm bore is built to accommodate 20mm spindles, making it compatible with standard heavy-duty trailer setups.
What sets this unit apart is the dual-bracket support design, which distributes load across a wider surface area. This minimises roller stress, improves keel alignment, and increases the life span of your trailer components.
