H2-2380 Concealed 140° Opening Hinge
This is a concealed hinge designed for industrial equipment, cabinets, and maintenance doors. The hinge is installed on the inner side of the door panel and cabinet body, with the main structure hidden inside the equipment when the door is closed. This design reduces the impact of exposed hardware on the appearance of the equipment and minimizes the risk of collision, scratching, and external damage to the hinge. The product features a long pin rotation structure, where the hinge pin serves as the rotation center during the opening and closing of the door panel. This simple and stable structure is suitable for industrial door panels that require long-term repetitive use. The mounting plates on both sides of the hinge are fixed using a multi-hole method, allowing for installation with screws on the inner sides of the door panel and cabinet frame. The concealed mounting design maintains a clean and flat front on the cabinet, making it especially suitable for industrial equipment that has requirements for appearance, equipment protection, and installation space.

FAQ
Can you send samples?
Yes, we can provide a few free samples for the customer, but we hope that the shipping cost can be covered by you.
What is the minimum order quantity?
Generally, the minimum order quantity is 200 PCS. However, if our inventory is sufficient, there is no minimum order quantity requirement.
Why is this hinge called a Heavy-Duty Concealed Hinge?
It is made of thick-walled cast SUS304 structure, providing significantly greater overall rigidity and load-bearing capacity compared to standard thin-sheet stamped concealed hinges. Additionally, it is installed within the door panel, classifying it as a heavy-duty concealed hinge.
Can the hinge be seen after the door is closed?
After normal installation, the hinge is located inside the door panel and frame, making it virtually invisible from the outside when the door is closed. This maintains a smooth appearance of the equipment while reducing the risk of external impacts on the hinge.
What is the maximum opening angle?
The structural design allows for an opening angle of approximately 90°, suitable for industrial cabinets and equipment doors. If the project requires opening angles of 120°, 180°, or larger, alternative hinge structures should be selected.
Which devices is this hinge suitable for?
Mainly suitable for electrical enclosures, automation equipment, machinery, railway equipment cabinets, energy storage cabinets, communication cabinets, vehicle equipment compartments, and various industrial doors requiring heavy loads, concealed mounting, and 90° opening.
