Black steel pergola support bracket for 4x4 wood posts, showing corner installation

Quiet strength, clean lines

A dark, architectural bracket that tucks into the top corner and makes a pergola read crisp and composed.

At the corner

Where shade begins

Purpose with presence

Long spans can sag and corners can look unfinished. The Pergola Support Bracket (for 4x4 Wood Posts) steadies that meeting point with a 45-degree arm and a square, tailored fit for dressed 4x4s. Pre-drilled holes and included #10 stainless screws make the connection straightforward, so the build moves quickly and cleanly.

The finished look

Corners set the tone. With laser-cut 14‑gauge steel and an advanced weather coating, this bracket holds form through harsh seasons while reading as a deliberate detail. Your pergola feels grounded—visually and structurally—so gatherings under it feel easy and assured.

For the builder-host

Homeowners shaping a pergola—freestanding or attached—who want a refined corner detail that also resists bowing on longer runs of wood.

How it’s used

Place one bracket on the top and one on the side of each corner to secure 4x4 posts and add a crisp accent that counters sag on longer spans.
