Build your dream outdoor structure with our 4"×4" Pergola Bracket Kit, where heavy-duty engineering meets effortless DIY installation. This two-piece 4-way corner bracket system is designed for mainstream 4"×4" beams (accommodating actual 3.6"×3.6" soft and hardwood), delivering robust support for gazebos, patio pergolas, and log cabins. Crafted from 2mm carbon steel plates with black powder coating, the reinforced 90° boot structure prevents breakage and deformation while full coverage shields posts from rainwater erosion—drainage holes at the base further prolong lifespan. The innovative sunshade sail attachment features convenient grommet holes, letting you easily mount shade sails to block harsh sunlight and shield interiors from rain, creating a comfortable, dry retreat. Installation is straightforward with 48 included drill tail screws (M4.8×50mm) and a comprehensive guide—no additional accessories needed. Resistant to heavy rain, snow, and strong winds, this bracket kit transforms your backyard into a stable, stylish oasis. Your ultimate outdoor building foundation starts here.
