Frequently Asked Questions

• Is this roller soft or hard?
  It’s made from hard nylon plastic — tough and durable.
• Can I use it on a painted hull?
  Yes, but since it’s a harder material, it’s better suited for alloy or metal hulls rather than delicate coatings.
• Does it fit standard trailer brackets?
  Yes, it fits all standard 16mm spindle brackets with its 17mm bore.
• Will the grey colour fade?
  Nope. It’s UV-stabilised to resist sun damage.
