Precision surface treatment further improves appearance consistency and long-term reliability, making it a dependable solution for modern door hardware applications.
Multi-Angle Control: This hydraulic door closer hinge supports a wide opening angle of up to 175°, allowing flexible access for different usage scenarios. The built-in automatic return function ensures the door gently closes once released, while the adjustable stop-angle feature allows installers to set controlled stopping positions between 90° and 160°. This multi-angle control makes the hinge suitable for doors that require both free movement and position holding, improving convenience and safety in daily operation.
Universal Installation: Designed with a universal structure, the hinge does not require differentiation between left-hand or right-hand doors. This symmetrical design simplifies installation planning, reduces inventory complexity for distributors, and saves time for contractors on-site. Whether used for inward or outward opening doors, the hinge delivers consistent performance, making it a practical and installer-friendly choice for a wide range of projects.

Step-by-Step Installation Guide
Prepare Door and Frame: Before installation, confirm that the door thickness exceeds 30mm to ensure sufficient structural support for the hydraulic hinge. Accurately mark the hinge positions on both the door and the frame, typically placing hinges 150mm from the top and bottom edges. For heavier or taller doors, an additional hinge positioned approximately 450mm from the top is recommended to improve load distribution and operational stability.
Create Slots (if needed): If the installation requires concealed mounting, machine precise slots on the side of the door panel facing the frame. All slots must be aligned on the same center line and machined to equal depth to prevent twisting or uneven stress on the hinge during operation. Proper slot preparation is critical for maintaining smooth hydraulic performance and ensuring long-term reliability.
Install Hinges: Position the hydraulic hinges into the prepared slots or directly onto the door surface, depending on the installation method. Mark the screw hole locations accurately, then drill pilot holes with a 3mm diameter to a depth of approximately 30mm. Secure the hinges firmly using self-tapping screws, ensuring they are tightened evenly to avoid misalignment.
Align Door and Frame: When mounting the door onto the frame, maintain a consistent gap of approximately 2mm at the top, along with an appropriate clearance at the bottom based on flooring conditions. Ensure that the upper and lower hinges are aligned along the same vertical center line, as improper alignment may affect closing performance and hydraulic efficiency.
Adjust Functionality: After installation, fine-tune the hinge performance using the provided hexagonal keys. A 5mm hex key is used to adjust the closing force—turning clockwise increases closing strength, while counterclockwise reduces it. A 1.5mm hex key allows switching between silent soft-close mode and the lock-in-place function, enabling customization based on door usage requirements.
Test Operation: Open and close the door several times to verify smooth movement, controlled closing speed, and correct stopping angles. Ensure the door closes fully without slamming and remains stable at preset angles when required. Make final adjustments if necessary to achieve optimal performance.
