VEVOR Pergola Bracket Kit 4x4 (Inner 3.6x3.6) — 4-Pack Black 3-Way Heavy-Duty Corner Brackets with Drainage & Screws

VEVOR's 4" x 4" three-way pergola bracket kit is a heavy-duty steel corner system that secures 3.6" x 3.6" wooden posts, protects them from weather, and simplifies building pergolas, gazebos, and outdoor beam structures.

Whether you're building a backyard pergola, repairing a patio cover, or assembling a log-cabin corner, this kit supplies four reinforced corner brackets plus the matching screws and drain features needed for lasting outdoor use. The brackets are stamped from 2 mm carbon steel, powder-coated black for corrosion resistance, and shaped to fully cover the post ends so timber is shielded from rain and sun. The package is finished with pre-punched grommet-style openings for attaching shade sails and drainage holes at the base to reduce water pooling.

How does this bracket kit protect wood from weathering?

The design fully envelopes the top of a square post to stop direct rain and sun exposure to the cut end of the timber, which is where rot typically begins. The powder-coated steel and reinforced boot structure also resist deformation under load and over time.

• Full-coverage boot shields the post end from direct rainfall and UV exposure
• Black powder-coat resists corrosion in outdoor conditions
• Drainage holes prevent standing water that accelerates rot
• Reinforced 90° corners improve structural rigidity under wind and snow

Will these brackets fit my 4" x 4" posts and what fasteners are included?

These brackets are sized for standard 4" x 4" posts with internal dimensions of about 3.6" x 3.6" (92 x 92 mm) and accommodate both softwoods and hardwoods. The kit includes abundant drill-tail screws so you can install the brackets without sourcing extra hardware.

• Internal bracket opening: ~3.6" x 3.6" (92 x 92 mm)
• Kit contents: 4 steel corner brackets, 80 drill-tail screws
• Screw size supplied: M4.8 x 50 mm for secure timber anchoring
• Installation guide included for step-by-step assembly

Can I attach shade sails or other accessories to these brackets?

Yes—the brackets include grommet-style attachment points to fasten sunshade sails, ropes, or light fixtures. These attachment holes are integrated into the steel shell so you can anchor accessories without compromising the bracket's protective coverage.

• Pre-punched attachment holes for shade sails and ropes
• Attachment points located away from drainage to prevent rust tracks
• Suitable for light fixtures and decorative hardware when used with proper anchors

How do these brackets speed up a DIY pergola build?

The brackets convert measured lumber into a ready-to-assemble frame: cut the posts to length, slide them into the corner boots, and secure with the included screws. Their full-coverage design removes the need for complicated joinery and provides a repeatable, robust corner detail for straight-forward builds.

• Slide-and-screw installation reduces time compared to custom joinery
• Consistent corner geometry for repeatable, square assembly
• Sturdy base minimizes the need for supplemental corner bracing

Who is this for: This VEVOR pergola bracket kit is ideal for homeowners, landscape contractors, and DIY builders who want a fast, durable solution for 4" x 4" post corners. It's well suited for outdoor structures—pergolas, patio covers, small gazebos, and cabin-style projects—where protecting the cut end of the post and simplifying joinery are priorities. If you need a weather-resistant, reinforced corner bracket with hardware included, this kit provides the essential pieces to build a stable, long-lasting outdoor framework.
