Hardware Hinge

If you're looking to buy concealed detachable hinges for switchgear cabinets, distribution boxes, or control enclosures, the Switchgear Door Hinge from Yitai Lock is available in carbon steel and 304 stainless steel, across two mounting hole configurations — round hole and slotted hole — in each material. The hinge body sits inside the cabinet frame channel rather than on the door face, keeping the exterior clean and hardware-free when the door is closed. At 108 mm overall height with a Φ6 mm barrel, it's built for the kind of regular door cycling that switchgear and distribution cabinet installations typically involve.

If you're buying side-mounted hinges for GGD electrical cabinets, second or third generation distribution cabinets, or power enclosures built on C-section profiles, the Power Cabinet Doors Side-Mount Bend Hinge from Yitai Lock covers a wide model range across four series — CL803, CL901, CL903, and CL233. All are black zinc alloy except the CL233, which is also available in sand blue zinc alloy and aluminum alloy. The bend profile on each model is designed to hook over the C-section frame lip, which is the standard mounting approach on GGD and similar industrial cabinet frames, and all models are screw-mounted through the front plate.

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.
