Description
Post Guide-On 65″ – Aluminum
These post-guide-ons utilize uprights that mount directly to your I-Beam trailer frame using stainless steel u-bolts, nuts, and washers for a fit that will work on virtually any size I-Beam frame. The metal uprights can be adjusted up to 19” out from each side of the trailer frame. Recommended for I-Beam trailer frames used in salt water due to the corrosion resistance of aluminum.
WARNING: To reduce the risk of nut seizure when using stainless steel hardware always apply a light coat of grease to threads prior to assembly.
