Pergola 4-Arm Post Bracket made of steel for 4x4 wood posts with included black screws

Quiet strength, open sky

A clean, black 4-arm junction that disappears into shadow while your pergola frames the light.

Make room to gather

The corner that holds the whole evening

Four arms, one intent

Big pergolas ask for certainty. The Pergola 4-Arm Post Bracket (for 4x4 Wood Posts) meets extra-wide or extra-deep spans with a calm, square geometry that keeps lines true. Pre-drilled holes and included #10 stainless screws turn a complex joint into a clear, orderly task. The result: a faster build and fewer second guesses.

Space opens up

When width or depth moves past 12 feet, gatherings grow with it—more shade, more table, more voices. This 14‑gauge steel bracket links posts and beams so the structure reads as one piece, weather after weather. Its dark finish recedes, leaving only the rhythm of wood and the comfort beneath.

For builders of lived-in yards

Homeowners extending a freestanding or attached pergola beyond 12 feet who want a crisp, durable joint for 4x4 dressed lumber.

How it’s put to work

Seat dressed 4x4 posts and beams into the four arms, then fasten through the pre-drilled 0.25-inch holes with the included #10 stainless screws.
