Installation / Usage Tips

Mount the guide-ons to your trailer crossmembers where they provide the best lead-in path for your boat. Start with the poles positioned wide and angled to guide the hull, then tighten all fasteners and test alignment with the boat at low speed. Keep the roller guide clean and periodically inspect for corrosion—reapply protective coating where needed. Tighten hardware after the first few launches and check alignment seasonally.
