Buying Guide
What crossmember sizes do I need?
Most 8″ bunk brackets support 1.5″x3″, 2″x3″, and 3″x3″ crossmembers. Confirm your trailer’s crossmember dimensions before purchasing to ensure a secure fit and minimal modification.
Why choose swivel top brackets?
Swivel top designs allow hull contour matching, reducing point loads and hull stress. They are beneficial for boats with uneven or angled hulls or when mounting bunk boards at varying heights.
What about corrosion resistance?
Galvanized or powder-coated finishes protect brackets from rust in saltwater and freshwater environments. Consider your trailer’s location and usage frequency when selecting finish type.
How many brackets should I buy?
For reliable support, plan to use at least two brackets per bunk board and distribute loads evenly across the trailer. If replacing all brackets, a full 4-pack or 8-pack kit provides consistent performance and easier installation.
Installation tips
- Verify bolt lengths and hardware compatibility with your trailer frame.
- Align bunk brackets to evenly support the hull and avoid contact with hull contours.
- Torque bolts to the manufacturer’s recommended specs to maintain stability during transit.
Maintenance considerations
Inspect brackets regularly for signs of wear, bending, or corrosion. Clean off salt buildup after exposure to saltwater and reapply protective coatings if needed to extend service life.
