• 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.
• 1.Applicable Door Thickness and Maximum Load Capacity: Suitable for door panels with a thickness of 0.98"- 1.50" (25-38mm); a pair of hinges supports a maximum load of 40kg.
• 304 stainless steel
• 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.
• 3. Adjustment for Spring Tension Integration, No Pin Fixing Necessary: Customize the tension based on door weight for various rebound speeds, guaranteeing effortless opening and closing. Easily set tension for swing doors with the hex wrench provided. Simply turn the wrench clockwise in the adjustment hole to increase spring tension for faster closure. To decrease tension and slow closing speed, tap the wrench in the hole with a tool.
