Build or Rebuild Your Trailer’s Bunk Support System The Extreme Max 12" Galvanized Swivel-Top Bunk Bracket is engineered for boat owners, DIY trailer builders, and repair specialists who want reliable, adjustable bunk support. Whether you're constructing a new trailer setup or replacing worn-out hardware, these brackets deliver durability and adjustability in one package. Customizable Swivel-Top Design Each bracket features an adjustable swivel-top plate that pivots to match the specific angle of your boat hull. This customization ensures proper bunk alignment, improved hull support, and secure loading and unloading at the ramp. Made for 3" x 3" Trailer Crossmembers Designed to clamp directly onto 3" x 3" trailer crossmembers, each bracket secures with the included U-bolt hardware for a strong, stable attachment point. Lag bolts (included) allow you to fasten the swivel top to your bunks for a complete setup. Freshwater-Focused Galvanized Construction Built from galvanized steel, these brackets resist rust and corrosion in freshwater environments such as lakes and rivers. (Note: Oxidation may occur in brackish or saltwater conditions.) Complete Hardware Kit (4-Pack) Each purchase includes four swivel-top bunk brackets and all necessary mounting hardware—everything needed to install the brackets onto your crossmember. (Bunks and boards not included.)
