Dasmiro Boat Trailer Bunk Bracket Kit — 4-Pack 10/12/14" Swivel Top, Galvanized Steel, Adjustable

Dasmiro's 4-pack swivel bunk bracket kit provides adjustable, galvanized steel support to secure bunks and protect hulls during trailer transport.

Designed for marine use, this kit combines heavy‑duty galvanized construction, extended U‑bolt threads and a swivel top to create a dependable bunk support solution for freshwater and saltwater trailers. Each bracket includes multiple mounting holes for precise height and angle adjustments, plus all mounting hardware for straightforward installation. The set supports a range of beam widths and adapts to different hull shapes to minimize pressure points while hauling your boat.

How does the swivel top improve hull contact and load distribution?

The swivel top allows the bunk plate to pivot so the wood or carpeted bunk can conform to the hull's contour, reducing localized pressure and helping the boat sit evenly on the trailer. This reduces shifting during transit and improves overall stability when launching and loading. The swivel action is simple and robust, built into a galvanized housing that resists corrosion.

• Pivoting bunk plate for better hull alignment
• Reduces stress points on hull gelcoat or fiberglass
• Improves trailer-to-boat fit during loading and transport

What materials and finishes protect these brackets from rust and wear?

Each bracket is formed from heavy‑duty steel and finished with galvanization to guard against oxidation in both fresh and saltwater environments. The galvanized layer delays corrosion and helps the bracket maintain strength over time. Welds and bends are engineered to resist deformation under typical towing loads.

• Hot-dip or zinc galvanization for corrosion resistance
• Reinforced welds for long-term structural integrity
• Durable finish suitable for marine exposure

Will these brackets fit my trailer crossbeam and different beam widths?

The kit includes extended U‑bolt threads to accommodate a broad range of crossbeam widths, letting you clamp securely without improvised adaptors. Multiple mounting hole positions on the bracket body give additional vertical adjustment so you can match bunk height and angle to your hull. Because hardware is included, you can typically mount these brackets to most common trailer beam profiles quickly.

• Extended U‑bolt threads fit varied beam widths
• Multiple holes for precise height and angle settings
• Complete hardware pack for faster installation

How easy is installation and what comes in the kit?

The Dasmiro kit ships with all required fasteners and U‑bolts, so installation is straightforward with basic tools. Mounting holes are predrilled and positioned for typical bunk board sizes, and instructions guide correct placement and torque. The result is a stable, adjustable bunk assembly that reduces setup time at the dock.

• Four swivel brackets sized for 10", 12" and 14" setups
• U‑bolts, nuts, washers and mounting hardware included
• Fits standard bunk boards and most trailer beams

Who is this for: This Dasmiro 4‑pack swivel bunk bracket kit is aimed at boat owners, trailer builders and marine service professionals who want a rugged, adjustable bunk support that resists corrosion and conforms to hull shapes. It’s a practical upgrade for small to medium trailers, personal watercraft trailers, and anyone replacing worn bunk hardware or improving load stability for safer launches and highway towing.
