The Modern Yard Horizontal Fence System Corner/Gate Post Concrete Bracket is designed specifically for corner and gate posts, providing a sturdy and reliable solution for installing these posts on concrete surfaces. Made from durable steel with a weather-resistant powder-coated finish, it ensures long-lasting performance and resilience in outdoor conditions. The bracket allows for hassle-free installation, eliminating the need to cut through concrete, and includes 12 crosshead self-tapping screws, 2 external hex cross screws, and a base cover for a secure and clean setup. For proper installation, the concrete surface must be at least 4.5 inches thick, and expansion bolts should be a minimum of 3 3/4 inches in length and 3/8 inches in diameter.
