Concealed Hinge with Studs

For anyone sourcing removable enclosure hinges from Yitai Lock, the Concealed Hinge with Studs CL060 handles both welding and nut mounting, and the screws are already included. There's a 19.8 mm slot on the mounting wing so you can fine-tune the position before locking it down — useful when you need the door to hang straight. The overall length comes in at 86 mm with a 70 mm hinge body and Φ5 mm barrel.

Structure and Dimensions

The Concealed Hinge with Studs runs 86 mm overall, with the main body taking up 70 mm of that and the mounting wing covering the rest. The barrel is Φ5 mm, and the stud itself has a Φ9.5 mm head, a 10 mm shaft, a 2 mm shoulder, and M5 threading — straightforward to engage with the frame channel nut.

For frame compatibility, the Concealed Hinge with Studs is designed for channels with an inner radius of R15.7 to R17.7 mm, a door panel clearance depth of ≤18.8 mm, a lateral reach of ≤21.4 mm, and a frame opening of >9.7 mm. The hinge body is 22.6 mm wide and the mounting wing is 25 mm wide — compact enough to sit cleanly within the frame without sticking out past the door face.

Installation and Mounting

The Concealed Hinge with Studs goes in with a combination of welding and nut mounting. The mounting wing gets welded to the door panel during fabrication, and the stud end engages the frame channel using the included M5 screws. The 19.8 mm slot on the wing gives you some room to shift the hinge position before tightening everything down, which makes door alignment a lot less fiddly during assembly.

Once it's all fixed in place, the Concealed Hinge with Studs still allows the door to come off when needed — just disengage the stud from the frame channel and the door lifts free. The welded wing stays on the door panel permanently, so taking the door off doesn't affect the hinge mounting at all. It's a handy feature for cabinets that need the door removed for wiring runs or internal access.

Application Scenarios

The Concealed Hinge with Studs shows up most often on distribution panel doors, switchgear enclosures, network cabinet doors, and industrial equipment cabinets where keeping the exterior clean matters. Since the hinge sits inside the frame, there's nothing visible on the outside when the door is shut — no protruding barrel, no exposed wing.

The detachable side of the Concealed Hinge with Studs also comes in handy for cabinets that get assembled in the workshop and shipped to site — the door can come off for transport and go back on once the cabinet is in position. The galvanized carbon steel finish is fine for standard indoor industrial environments, and at 86 mm the hinge fits the frame channel dimensions you'd typically find on distribution and switchgear enclosures.
