Tie Down Engineering Swivel Bolster Brackets, Hot-Dip Galvanized, Pair - Available in 10" and 12"
Tie Down Engineering Swivel Bolster Brackets, Hot-Dip Galvanized, Pair - Available in 10" and 12"
Tie Down Engineering Swivel Bolster Brackets give your boat trailer bunks and bolsters the ability to pivot and shift, so they follow the true shape of the hull instead of holding a fixed angle. Built from alloy steel and finished with a hot-dip galvanized coating, these brackets stand up to saltwater, freshwater, and constant load/unload cycles without rusting through. Each pair includes the mounting bolt and nylon lock nuts needed to install them, and the slotted design allows vertical adjustment so you can fine-tune bolster height and contact against the hull. Whether you are replacing worn factory brackets or upgrading a fixed-mount setup to a swiveling one, these brackets are a direct, hardware-included fix.

Sizes & Options
These swivel bolster brackets are sold by bracket length. The 10 inch version (part 81215) suits shorter bunk boards and smaller bolster setups, while the 12 inch version (part 81220) offers more coverage and support for larger bolsters or heavier hull sections. Measure your existing bracket or bolster mounting length before ordering to make sure the new pair lines up with your current hardware and frame spacing.
