C.E. Smith Double Slot Swivel Bolster Bracket Assembly - 13"

The C.E. Smith Double Slot Swivel Bolster Bracket Assembly—13" is a purpose-built roller bunk support system for boat trailers operating in demanding marine conditions. This bracket assembly delivers the adjustability and durability required to secure boats safely during transport and storage, with hot dip galvanized steel construction engineered to resist salt-air corrosion and prolonged water exposure.

The assembly combines two critical components: a 12-inch bolster bracket fabricated from 11-gauge steel with 2-1/2" width and 1/2"-wide slots spaced 4-3/4" apart, paired with a swivel bracket featuring a 1-3/8" x 3-1/2" bunk flange. The 1/2"-diameter swivel hole permits rotation and fine adjustment to match the contours of different hull shapes. This modular design allows users to configure support geometry to fit various boat types and trailer designs without custom fabrication or welding.

Weekend fishermen and serious boaters rely on this bracket assembly to distribute hull weight evenly across the bunk system, reducing stress concentration and minimizing risk of hull deformation during highway transport. The swivel mechanism accommodates minor misalignments between trailer frame and boat hull, absorbing vibration and protecting against chafing damage. C.E. Smith's galvanizing process provides long-term corrosion resistance in freshwater, saltwater, and mixed-use environments—critical for trailers exposed to coastal spray or brackish launch ramps where standard steel brackets fail rapidly.

This replacement bracket is compatible with C.E. Smith trailer systems and similar single-axle and tandem designs. Proper installation requires fasteners rated for the hull material and frame construction; verify mounting points before deployment. The 13-inch length accommodates mid-range beam widths common in bass boats, center consoles, and small cabin cruisers.
