The Vevor pergola bracket kit is designed to create strong, secure 90° corner connections for 4x4 wood posts with an actual inner fit of 3.5 x 3.5 inches. Built from 2 mm carbon steel with a black powder-coated finish, it is made to resist corrosion and outdoor wear. The wraparound design helps shield wood posts from rain and sun exposure, while drainage holes help reduce moisture buildup. Built-in hanging holes allow for sunshade sail attachment, and the included hardware supports installation on concrete, wood, and other surfaces. This kit is well suited for pergolas, gazebos, patios, and log cabin style structures.
