Frequently Asked Questions

• Q: Will this fit my trailer?
  A: If your winch post is 75mm wide and takes a 12mm bolt, you’re good to go!
• Q: What’s the bolt length?
  A: The included M12 bolt is 140mm long, and comes with nylock nuts.
• Q: Is the black poly non-marking?
  A: It’s generally safe, but on light-coloured fibreglass hulls, red poly is safer if you’re worried about marks.
• Q: Can I install this myself?
  A: Yes – it’s a bolt-through design and easy to DIY with basic tools.

Is This the Right Product for You?

Recommended if you:

• Have a 75mm wide trailer winch post
• Want a complete kit with bolt and nuts included
• Prefer a sleek black look over bright colours

Not recommended if you:

• Your trailer uses a wider winch carrier (e.g. 100mm)
• You want the softest possible contact – red poly is gentler
• You need a colour-coded or high-visibility roller
