Overview

A 4-pack of 3-way right-angle corner brackets with post bases for framing a pergola or gazebo from 4x4 lumber (actual 3.5 x 3.5 inch dimension). Aluminum alloy with a black powder coat finish, sold with the mounting hardware.

This is a structural hardware kit, not a finished pergola, and it only fits lumber that measures the true 3.5 by 3.5 inches of nominal 4x4 stock. The 3-way corner design is meant to replace notched or mitered wood joints at the point where a post meets two beams.

  • 4-pack of 3-way corner brackets with post bases
  • Fits 4x4 lumber at its actual 3.5 x 3.5 inch size
  • Aluminum alloy, black powder coat
  • Includes 128 hex screws and 16 expansion bolts

Who it's for

DIY builders framing a pergola or gazebo from standard nominal 4x4 posts who want pre-angled metal corners instead of cutting joints by hand. Not a fit for anyone working with a different actual post dimension or building freestanding without posts.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Skips cutting and notching wood joints by hand
  • Hardware included: 128 hex screws and 16 expansion bolts
  • Rust-resistant powder coated finish
  • Built-in holes for hanging a shade panel
What to check first
  • Only fits lumber at the true 3.5 x 3.5 inch dimension
  • Lumber still needs to be cut to length separately
  • No buyer reviews yet to confirm long-term outdoor wear

Performance notes

Each bracket forms a fixed 3-way right angle corner joining a post base to two beams, so the structure gets its rigidity from the bracket geometry rather than from cut wood joinery. The powder-coated aluminum alloy is built to resist rust in outdoor use.
