Build a coordinated timber frame around standard 4×4 lumber with 3 way corner brackets and matching post bases. Black powder coated carbon steel hardware joins the upper beams and supports the posts at the base, while 90° connector geometry organizes clean corner connections. Built in hanging holes add an attachment point for compatible shade sail hardware, making the set useful for pergolas, gazebos, courtyards, balconies, and similar outdoor structures.
4×4 Bracket Openings
Bracket channels are designed for standard 4×4 beams with actual lumber dimensions of 3.6"×3.6", helping you confirm fit before assembly.
Built In Shade Sail Hanging Hole
A hanging hole integrated into the corner bracket provides a dedicated point for compatible shade sail hardware when your pergola design calls for overhead fabric.
Full Cover 3 Way Corner
Steel sides cover the meeting ends of the horizontal beams and vertical post, keeping the corner connection contained within the bracket body.
4 Corner Brackets and 4 Post Bases
Included hardware provides 4 3 way corner brackets, 4 post bases, 16 expansion screws, and 144 drilling screws, bringing the main connection pieces together in the same kit.
4×4 corner brackets and post bases suit timber pergola style frames in settings such as courtyards, balconies, patios, parks, and outdoor dining areas.
