The Vevor pergola bracket kit is designed for 4x4 pergola and gazebo beam connections using actual 3.5" x 3.5" wood posts. This 2-piece 3-way T-shaped set is made from carbon steel with a black powder-coated finish for outdoor durability. Its full-wrap design helps improve stability while reducing exposure that can lead to cracking, warping, and water damage. Built-in shade sail attachment holes add flexibility for sun and rain protection. Screws are included for convenient installation.
