Make space for gathering

A quiet black bracket that disappears into the structure while the evenings stretch longer under your pergola.

Between two posts

Hold the line

Open-top ease

Pergola builds stall where posts need to meet cleanly. The Pergola Insert Bracket (for 4x4 Wood Posts) sits between existing posts so a 4x4 drops in from above, keeping everything inline and flush. Pre‑drilled holes and included #10 stainless screws remove the guesswork, while the solid 14‑gauge form keeps edges crisp.

Calm, straight, and true

When structure is square, the rest of the project flows—rafters align, privacy walls read as one plane, and railings feel composed. Advanced weather coating keeps the look consistent season after season, so the focus stays on dinner lights and conversation, not on fittings. It’s the small, sturdy detail that lets an outdoor room feel finished.

For the hands-on host

Homeowners shaping a pergola, privacy wall, or side railing with standard 4x4 dressed lumber who want clean lines and minimal fuss.

Where it works

Secure the bracket to two existing wood posts, then drop a 4x4 in from the top to create an inline rafter, privacy panel, or railing section.
