A.A Trailer Corner Bracket Kit — 16-Piece (8 Sets) Zinc-Plated Steel 4"×2.5" Right-Angle Brackets for Wood Panels

Heavy-duty A.A 16-piece corner bracket kit securely joins wooden trailer panels and stake-body gates at right angles.

These A.A wood panel side corner brackets come as eight left/right pairs (16 pieces total) designed for joining stake-body panels, tailgates, bulkheads and rack gates on utility trailers. Each bracket is zinc-plated steel to resist corrosion and sized to mount directly into wood; screws are not included so you can choose the fasteners that match your trailer's material and load requirements.

How do these brackets connect trailer panels and gates?

The brackets form a right-angle joint by fastening a left and right bracket to adjacent wooden panels, creating a rigid corner for stake bodies or gate frames. Their hole pattern aligns for through-bolting or wood screws, allowing quick assembly or repair without specialized tools.

• Kit includes 8 left and 8 right brackets for eight joints
• Each bracket measures 4" long and 2.5" wide for solid surface contact
• 5/16" diameter holes fit standard bolts or large wood screws
• Zinc plating adds a layer of rust resistance for outdoor use

What hardware and fasteners do I need to install them?

Screws or bolts are not included, so select corrosion-resistant fasteners sized for 5/16" holes and the thickness of your trailer wood. Use stainless or galvanized carriage bolts for through-bolted joints, or exterior-grade wood screws when fastening directly into the timber.

• Use 5/16" bolts with nuts and washers for strongest joints
• Exterior-grade wood screws for direct wood mounting
• Select fastener length to pass through bracket and fully engage wood
• Thread-lock or lock washers can prevent loosening from vibration

Will these brackets resist outdoor conditions and trailer use?

The brackets are formed from heavy-duty steel and finished with zinc plating to slow corrosion from rain and road salt. While zinc coating improves durability, choose appropriate metal fasteners and periodic inspection for high-salt or high-wear environments to maintain long-term performance.

• Zinc-plated finish for added corrosion resistance
• Heavy-gauge steel construction for structural support
• Suitable for typical outdoor trailer exposure with routine checks
• Replace or touch up damaged plating to avoid localized rust

How flexible are these for different trailer layouts and repairs?

The straight right-angle design fits a wide range of stake bodies, tailgates, and wood rack connections, making the set useful for both new builds and on-the-road repairs. Because each kit contains left and right pieces, you can create matched corners or swap out worn connectors without reworking the entire frame.

• Works with common wooden stake-body and gate panel thicknesses
• Left/right pairs accommodate mirrored corners and symmetric builds
• Good for spot repairs or outfitting multiple corners at once
• Install with standard shop tools—drill, wrench, and driver

Who is this for: This 16-piece A.A corner bracket kit is aimed at trailer owners, fabricators, and repair shops that handle wooden stake bodies, tailgates, and rack gates. If you build or maintain utility trailers and need a straightforward, corrosion-resistant solution to fasten panels at right angles—whether for new assembly or field repairs—this set supplies matched left and right brackets to cover eight corners with reliable hardware-ready holes.
