YVHFWOY 4x4 3-Way Pergola Brackets – 90° Corner Extension Kit for 4x4 Lumber, Black Powder Coated, DIY Gazebo Hardware (4 pcs)

YVHFWOY 4x4 3-Way Pergola Brackets: Durable, Outdoor-Ready Support

This pergola bracket kit from YVHFWOY is designed to support outdoor frames built with standard 4x4 lumber. Crafted from 2mm thick Q235B steel and finished with a black outdoor powder coating, the components combine rugged strength with weather-ready styling. The result is a dependable joinery system that resists deformation and wear while preserving a clean, low-profile look in any setting.

Key dimensions and fit help you plan with confidence. Each 3-Way bracket measures 7.87 by 7.87 by 6.3 inches, and the inner opening accommodates typical 4x4 columns (actual timber around 3.5 by 3.5 inches). The 90° right-angle design adds stability to grid-style pergola frames, especially when paired with additional brackets for larger layouts.
