Center of the gathering

A quiet cross of matte black steel that holds space for shade, conversation, and long summer dinners.

Make room

Where big porches begin

Calm strength

Large pergolas often stall at the middle—where beams, posts, and plans meet.
The Pergola 5-Arm Post Bracket (for 4x4 Wood Posts) resolves the crossroads with a single, precise form.
Laser-cut 14‑gauge steel, pre-drilled, and ready with stainless screws, it brings order to complex spans over 12 feet.

A single, certain connection

When the center holds, the rest follows.
This five‑arm hub lands cleanly on a 4x4 post and receives four beams with measured alignment, so the frame feels composed from the first turn of a screw.
Weather-ready coating and a considered layout let the structure age with the garden—not the hardware.

For the builder at home

Homeowners and makers extending a pergola beyond 12 feet in both directions who want a crisp, reliable center junction.

In practice

Set this bracket at the central post of a large freestanding or attached pergola to join four 4x4 beams and the vertical support in one aligned, secure point.
