Pergola 3-Arm Post Bracket for 6x6 wood posts, made from steel with pre-drilled holes, black screws included

Quiet strength, clean lines

A crisp black junction that squares the corner and sets the rhythm for open-air rooms.

Built where days slow down

Corners that gather people

A sculpted T of shadow

Pergola corners are where plans stall—measuring angles, wrestling joints, second-guessing stability. The Pergola 3-Arm Post Bracket (for 6x6 Wood Posts) fixes the geometry in one decisive move, using pre-drilled paths and included #10 screws to secure beams and post. Sized for 5.5 x 5.5 dressed lumber, it locks the layout so weekends are spent outside, not in the toolbox.

From parts to place

At each top corner, this 12‑gauge steel form becomes the anchor of a simple frame—shade above, a table below, friends drifting in and out. The matte black planes read as a thin shadow line against warm wood, a detail that feels both modern and unfussy. Weather-ready coating holds up when the season changes, keeping the structure—and the ritual—steady. Freestanding or attached, the corner is settled, and the space feels sure.

For the doer with a clear picture

Homeowners shaping a dependable pergola layout with clean, minimal hardware and straightforward assembly.

How it lives

Seat a 6x6 post in the vertical arm and two 6x6 beams in the horizontal arms to form a top corner of a freestanding or attached pergola.
