Getting your boat trailer set up right is key for safe towing. These galvanized bunk brackets from Colorfulway are built tough for the job. This is a 2-pack of heavy-duty brackets, each about 8 inches long. They're made from 4mm thick, high-strength steel with a galvanized exterior coating to fight off rust and corrosion from constant exposure to water. The smart design lets them fit multiple common crossmember sizes: 3\x3\, 2\x3\, and 1.5\x3\, giving you flexibility for your specific trailer setup. Installation is straightforward – they mount securely to the trailer frame with bolts (hardware not included), and no welding is needed. They provide a stable, ultra-stable base to attach your carpeted bunk boards, ensuring your boat is well-supported and stays aligned during transport and launching. A simple upgrade that adds a lot of durability and peace of mind for your watercraft adventures.
