faq
Frequently Asked Questions (FAQ)
- Q: Will this roller leave marks on my white hull?
A: No, the PVC material is non-marking and safe for white or light-coloured boat surfaces. - Q: Can this be used with a 16mm shaft?
A: Yes. The bore is 17mm, which fits most standard 16mm trailer spindles with a loose rotation. - Q: Is the aluminium core visible?
A: No – it’s embedded inside the PVC for strength, but fully encased for hull safety. - Q: How is this better than rubber rollers?
A: PVC is more shape-retentive, stain-resistant, and generally better for high-end hulls.
