Adjustable Boat Trailer Bunk Board Guide-on 61" Feet Rail w/Brackets Kit

Adjustable Boat Trailer Bunk Board Guide-On for 61" Rail with Brackets Kit

This adjustable boat trailer bunk board guide-on mounts to a 61 inch rail and helps center and align your boat during loading. The kit includes mounting brackets so the guide-on, sometimes called a bunk guide or bunk board guide-on, installs cleanly against the trailer frame. It suits boaters who want a steadier, more controlled approach onto the trailer.

Overview

This adjustable bunk board guide-on is made for boat trailers that run a 61 inch rail, giving the bunk a fixed vertical reference that keeps the hull centered as you drive on. The included brackets let you set the guide-on at the height and angle your hull needs, and the assembly is built to stay put through repeated launches and retrievals. It is aimed at boat owners handling routine trailer work who want predictable alignment without re-rigging the trailer.

Good To Know

Q: Will this guide-on fit any boat trailer? A: It is built for trailers that use a 61 inch rail and accept bolt-on guide-on brackets, so check your rail length and mounting points before ordering. Fit can vary by trailer model and rail configuration.

Q: Do I need to drill to install it? A: The kit includes brackets intended to mount onto a compatible rail, which may require drilling depending on the trailer frame. Confirm your rail width and hole pattern match the bracket setup first.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
