Frequently Asked Questions
- Is this roller suitable for aluminium boats?
Yes, but it is more ideal for fibreglass or painted boats due to its softer grey rubber. - What’s a “cotton reel” type roller?
It has a narrow centre and flared ends, allowing better keel alignment during launching or loading. - Is the shaft meant to spin inside the roller?
No, this one is designed so the shaft turns within the bracket. The roller is press-fit onto the shaft. - Is it UV resistant?
Yes, the rubber is UV stable and marine-grade.

Is This Roller Right for You?
Best for:
- Smaller trailers with cotton reel-style mounts
- Fibreglass or painted boats needing non-marking rollers
- Users looking for a direct press-fit onto a 16mm spindle
Not Ideal for:
- Spindles larger than 16mm – fit may be too tight
- Heavy boats needing softer poly rollers or full swivel support
Installation Tips:
- Align roller to spindle and gently tap into place – it’s a press-fit design
- Ensure shaft rotates freely in bracket
- Check keel alignment to prevent misload on ramps
