Keep your boat centered during the loading process, despite wind and waves, with these roller-style guide-ons. Corrosion-resistant posts support 9" rubber rollers with end caps. They fit trailer frames up to 3" wide x 4-1/4" tall.
Features:
Specs:
Adjustable boat guides can be fine-tuned to work with your boat and your trailer. The galvanized steel support posts mount horizontally on top of or below your trailer's frame rail. Just slide the posts into the boat guide supports and secure the posts so that the distance between the rollers correctly matches the width of your boat. The rubber roller guides help to center your boat during loading and to hold the boat during transport.
Galvanized Steel
Galvanized steel parts are hot-dipped in zinc after being stamped. This creates a coating that is typically 3 mil to 5 mil thick. This thick, all-around coating allows galvanized steel products to provide years of use without rusting or corroding.

The installation was quite easy and took less than one hour. The roller system has greatly improved the loading of our Alumacraft fishing boat. Under all conditions the rollers center the boat on the trailer and permit loading in one attempt aligning the keel of the watercraft exactly where it belongs. We no longer have to spend time at the launch site loading and reloading the boat when wind and wave conditions require two men and three oxen to keep the stern properly lined up. Great product!

After a year of having our guides they have worked great. It makes loading up our boat very easy, every time. We have our daughters loading up the boat now and they are doing it with out a problem.

The roller guides are good quality. It was very easy to install. They are just what you need on a windy day in Wisconson to guide the boat unto trailer.

The roller guide-ons have worked well for my boat. They make it easier to keep the boat straight on the trailer, which still can be a challenge especially on windy days.

A lifesaver! I frequently fish solo and these have repeatedly proven themselves to assist me in trailering in crosswinds or currents. They keep the stern of the boat from moving sideways, thus allowing it to stay centered on my bunks.
