About this item

• 4.Two-Way Opening and Automatic Closing: The double spring hinge allows the door to open in both directions and close automatically. When you push the door, the springs compress and store energy. Once you release the door, the springs release this energy, pulling the door back into its original position. This feature enhances convenience, safety, and energy efficiency, significantly improving traffic flow.
• 5.304 Stainless Steel, Matte Black Finish: Made from high-quality 304 stainless steel, it is rust-resistant, moisture-proof, and deformation-free, ensuring reliability and durability. The surface features an elegant matte black finish, offering a modern design that is both timeless and versatile.
• 1.Applicable Door Thickness and Maximum Load Capacity: Suitable for door panels with a thickness of 0.79"-1.42" (20-36mm); a pair of hinges supports a maximum load of 66lbs (30kg).
• 3. Built-in Spring Tension Control, No Need for Fixing Pin: The tension is adjustable based on the door's weight, allowing for various rebound speeds that promote effortless opening and closing. With the included hex wrench, you can swiftly and effortlessly adjust the desired tension for swing doors. To enhance spring tension and quicken the closing pace, insert the hex wrench into the adjustment hole and rotate it clockwise. Conversely, to decrease the spring tension and slow down the closing pace, place the hex wrench in the adjustment hole and gently tap it with a suitable tool.
• 2.Heavy-Duty Design, 3mm Thickened Steel Plate, Durable and Sturdy: Compared to regular 1.5mm thin hinges, this hinge uses a 3mm thick 304 stainless steel construction, providing stronger load-bearing capacity, making it especially suitable for heavy doors and high-frequency usage environments.
