Frequently Asked Questions
Q: How does the self-centering keel boat trailer roller bow stop work?
A: This 8-inch keel roller features built-in grooves that automatically guide your boat's keel into the correct position as you load it onto the trailer. The self-centering action ensures smooth, accurate placement every time — ideal for solo trailering or busy boat ramps.
Q: What material is the bow stop roller made from, and why does it matter?
