Yuleimy Boat Trailer Bunk Brackets 8-Pack — Galvanized Swivel Top, 3mm Solid Steel

Yuleimy 8 Pack Galvanized Swivel Top Angle Brackets are heavy‑duty, hot‑dip galvanized bunk brackets with a concave anti‑rotation swivel top designed to secure boat trailer bunks under marine conditions.

These swivel top angle brackets are engineered to strengthen trailer bunk setups and resist the corrosive effects of saltwater. Made from 3mm solid steel and finished with a marine‑grade galvanized coating, this set of eight brackets provides a durable mounting solution for boaters and trailer owners who need stability, corrosion resistance, and a locking swivel action to keep bunk boards aligned during transport.

How do these brackets prevent bunk rotation and shifting?

The brackets use a concave anti‑rotation design on the swivel top that helps lock the bunk board in place when subjected to road or water movement. Instead of a free‑spinning top, the shaped contact area provides interference that limits unwanted rotation and maintains the intended bunk angle.

• Concave swivel top for positive engagement
• Reduced lateral movement of bunk boards
• Maintains alignment through bumpy roads and launches

Are these brackets robust enough for heavy trailers and repeated launches?

Constructed from 3mm thick solid steel, these angle brackets are about 25% thicker than many standard options on the market, delivering increased stiffness and load resistance. The heavier gauge material reduces the chance of bending or deformation under prolonged load and repeated use.

• 3mm thickness for improved structural integrity
• Solid‑steel construction resists bending
• Ideal for frequent launching and heavy marine loads

Will these brackets hold up in saltwater and outdoor environments?

Yes — the brackets are finished with a hot‑dip galvanized coating that creates a durable physical barrier against moisture and corrosive elements. This treatment helps slow rust formation and extends usable life in coastal and freshwater conditions when properly installed and maintained.

• Marine‑grade hot‑dip galvanizing for corrosion resistance
• Suitable for freshwater and near‑coastal use
• Recommended periodic inspection for prolonged exposure

What mounting dimensions and hardware should I plan for?

Each bracket measures approximately 3.5" x 1.35" x 2" with top mounting holes spaced 2" center‑to‑center. The top flange accepts 3/8" diameter bolts; the swivel pivot accepts 1/2" bolts. This kit includes eight brackets only — fasteners are not supplied so choose bolts, nuts, and washers sized for your trailer and corrosion‑resistance needs.

• Overall bracket size ~3.5" x 1.35" x 2"
• Top hole centers: 2"; top bolts: 3/8" diameter
• Swivel pivot accepts 1/2" diameter bolt; hardware not included

Who is this for: Yuleimy’s 8 Pack Galvanized Swivel Top Angle Brackets are intended for boat owners, marine technicians, and trailer DIYers who need a tougher, corrosion‑resistant bunk mounting solution. If you replace or upgrade bunk hardware on small to medium trailers, launch frequently, or want a more stable swivel action that resists rotation, this eight‑piece set provides the base components for a reliable bunk support system. Remember to select appropriate stainless or galvanized hardware compatible with your trailer and operating environment.
