Tie Down Engineering Bunk Brackets: Marine-Grade Support for Every Hull

When it comes to keeping your boat secure and properly aligned on its trailer, few components matter more than the bunk bracket. Tie Down Engineering has been engineering marine trailering solutions since 1969, and their lineup of bunk brackets reflects decades of real-world refinement. Whether you're hauling a jon boat, a deep-V bass rig, or a personal watercraft, Tie Down offers a bracket configuration built to match your setup.

Built Tough: 11-Gauge Steel and Hot-Dip Galvanizing

The foundation of Tie Down's bunk bracket lineup is its construction quality. Crafted with 11-gauge steel, Tie Down's Bunk Brackets provide robust support, mounting 2" bunks on edge to ensure reliable boat alignment and protection during transport and storage. To stand up to the relentless demands of salt spray and freshwater immersion, these brackets are hot-dip galvanized for extra protection, built to withstand the elements and maintain their performance over time, even in harsh marine environments.

Adjustability That Fits Any Hull

One of the most practical features across Tie Down's bunk bracket range is its built-in vertical adjustability. The brackets are slotted for vertical adjustment, accommodating both standard and deep-V hulls — giving you the flexibility to customize the setup to match your boat's specific requirements. The signature Bolster Swivel Brackets take this a step further: these brackets are designed with slotted holes for easy vertical adjustment, while added non-slip dimples provide excellent stability, preventing unwanted movement and enhancing load capacity.

A Bracket for Every Application

Tie Down's bunk bracket catalog spans a wide range of hull types and trailer configurations. The Bolster Swivel Brackets are available in three sizes — 8", 10", and 12" — allowing you to find the perfect fit for your boat's bunk boards. For heavier setups or trailers that need wider adjustment range, the 9-1/2" bracket with a 6" slot length offers a precise fit for your bunks.

For personal watercraft and skiff owners, Tie Down offers a dedicated solution. The innovative light-duty bolster PWC Bunk Brackets are specially designed for personal watercraft and skiff trailers. The unique design allows for easy and precise bunk angle adjustments, and this smart feature eliminates the need for a swivel bracket, streamlining your trailer setup.

Rounding out the lineup, the Wobble Roller Bunk Bracket is used to mount the replacement Wobble Roller Assembly to the Wobble Roller Bunk Assembly, while Split Panel Brackets are sold in pairs — right and left — to accommodate any size roller length, with a slot that allows vertical adjustment for stabilizing the boat on the trailer.

Ready-to-Install Hardware

Tie Down understands that time on the water beats time in the driveway. Packaging options include pairs of brackets with swivel brackets, bolts, and nyloc nuts for convenient installation. Brackets are also available in bulk (one bracket only), providing flexibility for your specific needs. Whether you're replacing a single bracket or outfitting an entire trailer, the selection and packaging options make it easy to get exactly what you need.
