Andorm Boat Trailer Bunk Bracket Kit 4-Pack 8" Galvanized Swivel Top — Heavy-Duty, Clamp-On

This four-piece bracket set gives boat owners a corrosion-resistant, adjustable solution for supporting bunk boards and guiding hulls during launching, loading, and trailering. Each bracket is made from thick steel and finished in hot-dip-style galvanization to resist saltwater and freshwater exposure. The swivel-head design lets you tilt bunks to match hull contours without fabricating custom mounts, while the universal clamp-style base accommodates the most common crossmember sizes used on boat trailers.

How does the swivel top improve boat support and alignment?

The swivel top rotates so you can angle bunks precisely to your boat’s keel and chines, reducing hull pressure points and making centering easier when loading. It’s particularly useful for trailers hauling different boats or for trailers that need to adapt to shifting bunk positions.

• Swivel head for multi-angle adjustment
• Secure locking mechanism holds chosen angle during transport
• Improves hull contact distribution for safer launches

Will these brackets fit my trailer crossmembers?

These brackets are designed to clamp around common rectangular crossmembers sized 1.5x3, 2x3, and 3x3 inches, making them compatible with the majority of aftermarket and factory trailer frames. No welding or cutting is required for the typical installation; the clamp base grips the member and is fastened with included hardware.

• Compatible with 1.5x3, 2x3, and 3x3 crossmembers
• Clamping base eliminates need for fabrication
• Included hardware simplifies mounting process

How durable and weather-resistant are these galvanized brackets?

Each bracket is fabricated from heavy-gauge steel and finished with a full galvanized coating to resist rust in marine environments. That protective layer helps prevent corrosion from road salt, spray, and regular exposure to freshwater, extending service life compared with plain steel parts.

• Heavy-duty steel construction for long-term strength
• Galvanized finish protects against rust and corrosion
• Suitable for freshwater and light saltwater trailering

How easy is installation and what tools are needed?

Installation is straightforward: position the bracket on the crossmember, tighten the clamp hardware, and attach your bunk board to the swivel top. Typical installs require common hand tools—wrenches or sockets—and the kit is supplied with the parts needed for assembly, so you can complete the job quickly at a driveway or service bay.

• Simple clamp-on design—no welding required
• Uses standard hand tools (wrench/socket)
• Includes parts for mounting and adjustment

Who is this for? Boat owners, trailer repair shops, and DIYers who need a robust, adjustable bunk mounting solution will benefit from this Andorm 4-pack. It’s ideal for people who trail different boats, retrofit older trailers, or want a corrosion-resistant upgrade without custom fabrication. The kit balances durability, adjustability, and straightforward installation for both weekend projects and professional trailer maintenance.
