Frequently Asked Questions

• Q: What does “Double Bracket” mean here?
  A: It refers to a wider, reinforced roller bracket with dual side plates for better load distribution and stability.
• Q: Why is the roller bore 26mm but it suits a 19mm spindle?
  A: The bracket assembly is designed to mount securely with 19mm spindles, while the roller bore provides a smooth spin fit and shock tolerance.
• Q: Will this work for a small boat?
  A: It’s overkill for small tinnies—designed for heavy vessels or wide hulls needing robust central support.
