Quiet strength, clean lines

A matte, architectural T that disappears into shadow and lets the pergola take the stage.

Make room

Where the wall pauses and life moves through

A precise split

Long privacy slats can tire and sag; walkways get blocked by a continuous wall. The Pergola 3-Arm T Bracket (for 4x4 Wood Posts) introduces a measured break—dividing one run into two sections or framing a clear doorway. Its 14‑gauge steel body and pre-drilled pattern create a tidy, confident junction that feels considered rather than improvised.

Order in the open air

Outdoor rooms work when structure guides the flow. With defined spans and a purposeful opening, conversations drift, breezes move, and the space reads finished. The bracket keeps lines crisp so gatherings feel effortless season after season.

For the builder-host

Anyone shaping a pergola that needs a clean split in a privacy wall or a welcoming passage without visual clutter.

Put it to work

Create a doorway or shorten slat spans on a 4x4 pergola wall by setting posts into the three arms and fastening through the pre-drilled holes with the included #10 stainless screws.
