XYADX Pergola Brackets Kit 4x4 (3.7x3.7) — 4-Pack 3‑Way Heavy‑Duty Corner Brackets with Drainage, Black Powder Coat

These powder-coated steel corner brackets from XYADX are built to make outdoor woodworking quicker and more durable. Each bracket accepts a standard 4x4 post with an internal footprint of 3.7 x 3.7 inches (94 x 94 mm), offers integrated drainage to protect timber, and includes ports for attaching shade cloth or sunshades. The kit contains four 90° right-angle brackets designed for easy, repeatable alignment, giving you a solid foundation for a variety of backyard structures.

How do these brackets protect wood from water and weather?

The XYADX design uses precision-cut openings that let water drain away instead of pooling inside the bracket. That reduces moisture exposure to the post and lowers the chance of rot where wood meets metal.

• Drainage slots prevent standing water in the post cavity
• Black powder coating offers corrosion resistance outdoors
• Raised mounting areas keep the post slightly separated from direct metal contact

What makes installation simple for a DIYer?

These are right-angle, three-way corner brackets made to accept pre-cut 4x4 posts: cut your lumber, slide pieces into the bracket, and fasten with self-drilling screws. The precise 90° edges help you align corners quickly without time-consuming measuring adjustments.

• Self-drilling screw compatibility saves pre-drilling steps
• Clear 3.7 x 3.7 inner dimension fits standard 4x4 timber
• Symmetrical openings simplify repeatable, square assembly

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

Yes—the XYADX brackets feature dedicated connection ports for shade cloth, ropes, or small hardware so you can add sunshade or privacy screens without drilling into your posts. These ports make it easier to customize your pergola for comfort and function.

• Pre-formed ports align with common shade attachment hardware
• Reinforced edges around ports reduce wear on fabric ties or hooks
• Allows shade addition without altering structural timber

How versatile are these brackets for different outdoor structures?

Designed for terraces, balconies, patios, lawns, and light commercial settings, the XYADX brackets work for pergolas, arbors, gazebo frames, and screened porches. Their heavy-gauge steel construction supports typical overhead beams while remaining suitable for DIY projects and small contractors.

• Compatible with pergolas, gazebos, outdoor rooms, and trellises
• Suitable for residential and light commercial installations
• Four-bracket pack supports a single-corner-focused project or paired with more sets for full-frame builds
