Quiet strength at the corner

A crisp, black junction where timbers meet and a yard becomes a room.

Build the gathering line

The moment a frame becomes a place

Three arms, one calm silhouette

Starting a pergola can feel like guesswork—angles, joints, and fasteners battling for attention. The Pergola 3-Arm Post Bracket (for 4x4 Wood Posts) brings the corners into focus, aligning posts and beams with simple, square confidence. Pre-drilled faces and included #10 stainless steel screws remove the scramble for parts and placement. Premium 14‑gauge steel with weather coating keeps the structure composed through the seasons.

Order in open air

Corners set the tone for every meal, project, and late talk that happens beneath them. When the frame is sure, people relax—string lights hang straighter, shade lands where you want it, and the evening lingers. This bracket shortens build time by as much as 75%, so the backyard shifts from plan to practice faster.

For the hands-on host

Homeowners shaping a clean, durable pergola layout with 4x4 dressed lumber and a modern, black hardware touch.

How it fits

Seat a 4x4 post in the vertical arm and slide two 4x4 beams into the horizontal arms to form a top corner on freestanding or attached pergola frames.
