About this item

• 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).
• 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.
• 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.Integrated Spring Tension Adjustment, No Fixing Pin Required: The tension can be adjusted according to the weight of the door to achieve different rebound speeds, ensuring smooth opening and closing. You can quickly and easily set the required tension for swing doors using the included hex wrench. Insert the hex wrench into the adjustment hole and turn it clockwise to increase the spring tension, which speeds up the closing speed.To release the spring tension and slow down the closing speed, insert the hex wrench into the adjustment hole and tap it lightly with an appropriate tool.
