ITEM SPECIFICS
The BDA103 is the heavyweight champion of the Vee roller family. Built to tame large hulls and brutal launching conditions, this 12-inch concave roller made from hard blue polyethylene delivers uncompromised keel support for heavy-duty trailers.
With a bore size of 26mm, it comfortably fits 25mm spindles and offers smooth rotation even under substantial weight. Its concave profile naturally guides the keel toward center during launch or retrieval, making it the perfect match for wide fibreglass vessels.
What sets it apart from its sibling (BDA102)? The addition of a standard galvanised clamp-on bracket with 75x50mm adjusters — giving installers more flexibility and strength for mounting.

Frequently Asked Questions
- How is BDA103 different from BDA102?
BDA103 comes with a standard bracket and clamp-on stem adjusters; BDA102 is spindle-based only. - Can I use this with a 16mm spindle?
Not recommended. The 26mm bore is designed for 25mm spindles — too much play for smaller ones. - Will the roller mark my boat?
Nope. The blue polyethylene is non-marking and perfect for fibreglass hulls. - Is the bracket adjustable?
Yes — clamp-on style with 75x50mm adjusters gives you flexibility during installation.
