Installation Guide

1. Ensure the boat is safely secured off the trailer or the trailer is properly supported to prevent movement.
2. Loosen and remove the nuts and bolts that secure the existing bow roller's shaft.

4. Clean any dirt or corrosion from the bow stop bracket where the new roller will be seated.
5. Position the new bow roller between the mounting brackets, aligning the central hole.
6. Slide the 1/2" shaft through the brackets and the new roller.
7. Re-install and securely tighten the nuts and bolts on the shaft.
8. Verify the roller spins freely and is properly aligned with the boat's bow.

Troubleshooting & FAQ

Q: How do I know if this roller will fit my trailer?

A: First, measure the width of your current roller (typically 3" or 4"). Second, confirm your trailer's bow stop assembly uses a 1/2" diameter shaft for mounting. This assembly is a direct replacement for Tie Down 86287 and specific GlückMarine models with these dimensions.

Q: What is the difference between the PVC and TPU materials?

A: Both PVC and TPU are highly durable, non-marking materials specifically chosen for their resilience in marine environments. The material often varies by brand (e.g., Tie Down uses PVC). Both provide excellent resistance to UV rays, saltwater, and impact, protecting your boat's hull.

Q: My original roller was a different color. Does that matter for fitment?

A: No, the color (such as Amber, Yellow, or Blue) is typically a cosmetic choice by the manufacturer and does not affect the roller's function. As long as the width and shaft diameter dimensions match your requirements, it will perform correctly.
