Hardware Hinge

Yitai Lock is a technologically mature manufacturing company whose core products are all kinds of hardware locks and Spring bolts latch hinges, which are widely used in household and engineering fields. The Spring bolts latch hinges provide extremely high connection strength through welded fixing to meet the stringent requirements of reliability and durability for power equipment, communication cabinets, and so on.

Yitai Lock's products cover hardware locks and Cabinet Door Pivot Central Shaft Hinges, serving both domestic and international markets. This removable male and female hinges is a connecting part for electrical boxes and cabinets, which adopts a unique plug-and-play structure to realize quick dismantling and precise positioning of the cabinet door.

The Triple-Bend Hinge for Industrial Cabinets from Yitai Lock is available in galvanized carbon steel and 304 stainless steel with a vibratory polish — a solid option if you're buying cabinet door hinges for electrical distribution panels, switchgear enclosures, or industrial equipment cabinets. It opens to 90° and goes on with four countersunk screws, no welding needed, with screw heads sitting flush once fitted. It opens to 90° and mounts with four countersunk screws — no welding required — which makes installation straightforward and keeps the screw heads flush with the leaf surface. The asymmetric leaf design, with one side at 14.5 mm and the other at 11.5 mm, suits frame-and-door configurations where the two mounting surfaces have different available widths.

The RMU Cabinet Zinc Alloy Hinge from Yitai Lock is a welded zinc alloy hinge designed for ring main unit cabinets, electrical distribution boxes, and industrial control enclosures, available in black and bright chrome. What sets this hinge apart from most cabinet hinges is the 270° opening angle — the door can swing past flat and fold back almost fully alongside the cabinet frame, which is genuinely useful in RMU installations where full access to the interior is needed without the door getting in the way. If you're buying hinges for ring main units or switchgear enclosures, it's a detail worth paying attention to.

The Fully Concealed Stainless Steel Hinge from Yitai Lock is a welded concealed hinge for distribution cabinets and control equipment enclosures, available in carbon steel and stainless steel, each with a choice of black or red clamp. The hinge body sits entirely within the door frame channel when the door is closed — nothing visible on the exterior — which is the defining feature of this type and why it gets specified on cabinets where a clean, uninterrupted door face is part of the requirement. It opens to 90° and is compatible with Rittal cabinet frames, making it a practical option for manufacturers already working within that system.

If you need a detachable concealed hinge for distribution panels, switchgear enclosures, or industrial network cabinets, the Concealed Hinge with Studs from Yitai Lock is worth checking out. It's a single-spec carbon steel hinge that sits inside the door frame channel rather than on the face — the M5 stud with a Φ9.5 mm head drops into the frame and stays out of sight once the door is closed. It weighs 83g, so it's solid enough for industrial use without being bulky.
