Automatic Door Closer with Flex-Stop Feature, Adjustable Hydraulic Closer for Doors 35-65kg, Aluminum Alloy, High-Performance 60SiMn Spring, Speed Adjustable, EN1154 Certified for Home Commercial Use

• 🏆 【Professional-Grade Durability with “Flex-Stop” Function】 Experience unparalleled convenience and control. Our door closer features an exclusive “Flex-Stop” that holds the door open beyond 90° for hands-free passage, then smoothly closes when the angle is reduced. Built to last with a high-performance 60SiMn spring and imported hydraulic oil, it remains unchanged after 2 million uses – ensuring decades of reliable performance.
• 🔧 【Precision Engineered Core for Ultimate Reliability】 Every component is over-engineered for endurance. The piston (45# steel) and gears (20Cr steel) undergo specialized high-frequency quenching (HRC 45-55°) , dramatically increasing wear and fatigue resistance. This ensures quiet, smooth, and consistent closing for long-term use, effectively preventing oil leaks and mechanical failures.
• 🚪 【Wide Compatibility & Complete Installation Kit】 Designed as a universal, non-handed solution for both left and right-opening doors, this closer works perfectly with metal doors, fire doors, wooden doors, and more. It suits a broad range of door weights (35-65kg) and widths. The package includes all necessary mounting screws and a detailed template for straightforward installation. Note: For the Flex-Stop feature to work, the door and frame must be on the same plane (offset less than 5cm).
• ⚙️ 【Fully Adjustable & Leak-Proof Assurance】 Gain complete control over your door's movement. Two independent valves allow precise adjustment of closing and latching speeds to match any environment. The imported sealing rings are highly resistant to wear, aging, and cracking, providing a leak-proof guarantee that maintains optimal performance and cleanliness over time.
• ✅ 【Certified Quality & Versatile Application】 Manufactured to the highest standards, this closer complies with EN1154 certification for safety and performance. The combination of rigorous testing, premium corrosion-resistant aluminum alloy body, and commercial-grade construction makes it the ideal choice for hospitals, schools, shopping malls, hotels, offices, and residential properties. A reliable solution for any setting.
