(4)10" Boat Trailer Swivel Top Bunk Board Bracket Bolster Adjustable Bracket Kit

Swivel Top Bunk Board Bracket Kit for Boat Trailers

This 4-piece swivel top bunk board bracket kit lets you mount and adjust trailer bunk boards with a pivoting head that self-aligns to the hull for even support.

Overview

This swivel top bunk board bracket kit gives boat trailer owners a practical way to mount and fine-tune bunk boards. The pivoting swivel head tilts to match the hull angle, so each bunk board bracket carries the load evenly instead of digging into one edge. Sold as a set of four, this adjustable bracket kit suits trailer owners replacing worn hardware or building new bunks from scratch.

Built For Performance

• Swivel top head pivots to follow the hull angle for even bunk board contact
• Adjustable mounting slots allow height and angle fine-tuning during setup
• Four brackets per kit, enough for a full bunk board install or spares
• Bolster-style design supports 10 inch wide bunk boards
• Bolt-on installation with standard trailer hardware
• Suited to fresh and saltwater trailer use

On-The-Job Use

• Replacing rusted or bent bunk brackets on an existing boat trailer
• Building new bunk boards for a rebuilt or modified trailer
• Adjusting hull support height when loading characteristics change
• Keeping spares on hand for trailer maintenance

Specs At A Glance

Good To Know

Q: Do these brackets include mounting bolts? A: The kit covers the four swivel top brackets, so check your existing hardware or order bolts separately if you are building from scratch.

Q: Will the swivel head fit my hull shape? A: The pivoting top is designed to self-align against most bunk-supported hulls, and the adjustable slots let you set final height and angle during installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
