Grehitk 15° Slanted Pergola Bracket Kit for 4x4 Lumber — 6 Heavy-Duty Steel Wall-Mount Brackets with Hardware

Grehitk's pergola bracket kit is a set of six heavy-duty 15° slanted steel wall-mount brackets engineered to secure 4"x4" (actual 3.5"x3.5") lumber for sloped pergola roofs and wall-extension structures.

If you want a durable, rust-resistant way to attach a slanted pergola roof or extend a pergola from a wall, this bracket kit supplies angled support, hardware, and compatibility for common 4x4 posts. Each bracket is made from thickened plate steel to resist deformation, and the 15° pitch is designed to promote water runoff and a tidy roofline. The kit includes the exact fasteners needed to anchor the brackets to masonry or wood and to mount posts securely.

How do these brackets hold up in outdoor conditions?

The Grehitk brackets are formed from 0.1" thick plate steel to increase structural strength and resist bending under load. A quality finish and robust construction help protect them from typical outdoor stresses like wind and weight from roofing materials.

• 0.1" thickened steel plate for improved rigidity
• Welded shoulders and flange design for load distribution
• Compatible fasteners included for secure anchoring

Will this kit fit my 4x4 posts and wall type?

The brackets are sized for nominal 4"x4" posts (actual 3.5"x3.5") and include the necessary lag bolts and expansion bolts for common wall substrates. Whether attaching to wood framing, masonry, or concrete, the provided hardware covers typical installations, but confirm your wall material and local code before beginning.

• Designed for 4x4 lumber (actual 3.5" x 3.5")
• Hardware set: M10 expansion bolts, M8 hex screws, M5*85 hex screws
• Works for deck, patio, or garden wall mount applications

How does the 15° slanted design benefit a pergola?

The 15° slant creates a gentle roof pitch that encourages efficient water runoff while keeping a low-profile aesthetic. This angle offers a balance between appearance and function, reducing pooling on top beams and helping protect the structure beneath during rain.

• 15° angle promotes rainwater shedding
• Maintains a clean, modern roofline for extensions
• Suitable for shallow-pitch coverings such as polycarbonate or slatted roofs

What comes in the box and how simple is assembly?

The kit ships with six steel brackets and a complete set of fasteners so you can cut lumber to length and assemble without sourcing extra hardware. Basic tools and common DIY skills are sufficient for most installations; follow safe anchoring practices and pre-drill as required for your wall type.

• 6 Grehitk 15° slanted pergola brackets
• 8x M10 expansion bolts for wall anchoring
• 8x M8 hexagon screws and M5*85 hex screws for post attachment

Who is this for: The Grehitk pergola bracket kit is aimed at homeowners and DIY builders who want a reliable, angled wall-mount solution for 4x4 timber pergolas, small roof extensions, or rustic log-cabin style outdoor covers. It's well suited for users who prefer ready-made metal hardware to speed installation, contractors fitting compact pergolas, and renovators updating patios or garden structures. If you require heavier load capacities, larger lumber sizes, or custom engineered attachments, consult a structural professional before installation.
