Weather-ready construction

The kit benefits from WeatherGuard Protection—a triple-layer finish combining zinc plating, black chromate dip, and baked-on enamel. This combination is designed to resist corrosion and stand up to harsh outdoor conditions, including exposure to treated lumber. It’s the kind of durability that supports long-term performance without requiring frequent maintenance.

• Three-layer protection provides superior corrosion resistance
• Suitable for wood, steel, and vinyl gates
• Designed for maintenance-free operation after proper installation

Security and ease of use

The self-closing hinges automatically return your gate to the closed position, improving boundary control and gate security in busy areas or pet spaces. The included tension-adjustment tool lets you tailor the spring force to match your gate weight and swing, helping you achieve a balanced feel during use.

• Engineered 50 lb per pair load capacity for common residential gates
• Single latch component provides secure closure
• Comprehensive hardware kit for straightforward installation

Designed to endure weather and resist the corrosive effects of pressure-treated lumber, this gate kit reflects National Hardware’s long history of outdoor gate hardware reliability.
