Product Details

The Tie Down Engineering 86103 is a heavy-duty 48-inch PVC boat trailer guide-on kit designed to simplify and safeguard the process of loading and launching your boat. Standing 48 inches tall, these guide posts provide a clear visual reference when backing your trailer down the ramp, helping you align your boat accurately every time.

Each post is constructed from non-marring PVC pipe, protecting your hull from scratches and scuffs on contact. For added rigidity and impact resistance, the PVC is internally reinforced with metal tubing extending up into the tube. A bright orange end cap tops each post, maximizing visibility for a wider, easier-to-target loading zone. The posts are angled at a 13-degree slant, creating a wider opening that helps funnel your boat onto the trailer with less guesswork.

Key Features:

  • 48-inch non-marring PVC guide posts — sold as a pair
  • Internal metal tubing reinforcement for strength and impact resistance
  • 13-degree slant angle for a wider, more forgiving loading target
  • Highly visible bright orange end caps
  • Fits trailer frame tubes sized 2"x3", 2"x4", 3"x3", and 3"x4"
  • Adjustable up to 11 inches from the trailer frame on each side
  • Easy bolt-on installation — no cutting or drilling required
  • Galvanized mounting brackets and zinc-plated U-bolts and nuts for corrosion resistance
  • All mounting hardware and installation instructions included
  • No lights (light-free version)

The complete hardware kit installs with standard tools and requires no modification to your trailer frame. Galvanized and zinc-plated hardware ensures long-lasting corrosion protection in harsh marine environments. Ideal for recreational and heavy-use trailering applications.
