Distribution Panel Removable Hinge

For those sourcing control cabinet hardware from Yitai Lock in quantity, the Distribution Panel Removable Hinge CL250 series is worth comparing across models before placing an order, since the structural design is consistent but the dimensions vary between models. The removable design means the door can be lifted off without tools once installed, which is a practical feature for assembly lines and field maintenance alike. Both installation methods — screw and weld — are supported, so the hinge fits into most fabrication workflows without modification.

Model Options and Dimensions

The Distribution Panel Removable Hinge CL250 series covers four models with the same basic structure but different sizes. The CL250-1 has an overall height of 80 mm with a hinge body of 66 mm, a total depth of 33 mm, and a barrel diameter of Φ6 mm. The CL250-2 shares the 80 mm overall height and uses a 60 mm body length, a depth of 39 mm or more, and a Φ5 mm barrel with two Φ6.5 mm mounting holes spaced 6.5 × 12 mm apart.

The CL250-3 and CL250-4 are the more compact options in the Distribution Panel Removable Hinge range. Both have a hinge body height of 36 mm and an overall height of 60 mm, with a 14.5 mm base width and Φ5 mm barrel. The CL250-3 has a depth of 32.5 mm while the CL250-4 goes to 38.5 mm. All four models use a Φ4 open retaining ring to secure the pin in place.

Rod Types and Opening Angle

One of the more practical details on the Distribution Panel Removable Hinge is the choice of three rod types: knurled, straight, and curved. The knurled rod adds grip texture to the pin, which helps resist loosening under vibration. The straight rod is the standard option and suits most general enclosure applications. The curved rod is shaped to make pin removal easier by hand, which can be useful where the hinge is accessed frequently or in tight spaces.

All rod types on the Distribution Panel Removable Hinge work with the same Φ4 open retaining ring that locks the pin once seated. The opening angle across the entire CL250 series is approximately 120°, which gives enough clearance for most cabinet door access needs without requiring a full 180° swing.

Installation and Mounting

The Distribution Panel Removable Hinge supports two installation methods — screw mounting and welding — which means it can be used in both fabricated sheet metal enclosures and bolt-together cabinet assemblies. For screw mounting, the CL250-1 uses a single Φ6.5 mm slot, while the CL250-2 and the CL250-3/4 models use oval slots or dual holes that allow some positional adjustment during installation.

Once installed, the Distribution Panel Removable Hinge allows the door leaf to be removed by pulling the pin — no tools needed. This makes it well suited to enclosures that require periodic door removal for wiring access or internal maintenance. The retaining ring keeps the pin from working loose during regular use, so there's no risk of the door coming off unexpectedly mid-operation.

Application Scenarios

The Distribution Panel Removable Hinge shows up most often on distribution boxes, control cabinet doors, and industrial equipment enclosures — anywhere a door needs to come off cleanly without dismantling the frame. The 120° opening angle is enough for comfortable access to panel interiors in most installations, and since both screw mounting and welding are supported, it fits into most cabinet fabrication setups without any adjustment.On the material side, the zinc-plated carbon steel Distribution Panel Removable Hinge is the go-to for standard indoor enclosures in dry conditions. The 304 stainless steel version is the better pick for outdoor switchgear, coastal installations, or anywhere the cabinet is going to deal with moisture or corrosion over time.The 304 stainless steel version is the better fit for outdoor switchgear, coastal installations, or any application where the enclosure is exposed to humidity or corrosive conditions over time.

FAQ

Q1: What models are included in the CL250 series?

The CL250 series includes four models: CL250-1, CL250-2, CL250-3, and CL250-4. All share the same structural design and opening angle — the differences between them are in size and mounting hole configuration. Select based on your door panel dimensions and load requirements.

Q2: What is the opening angle of the CL250 hinge?

All four CL250 models open to approximately 120°. This is consistent across the full series regardless of model size or material.

Q3: What rod types are available?

The CL250 hinge is available with three rod types: knurled, straight, and curved. Knurled rods resist loosening under vibration; straight rods are the standard option; curved rods make pin removal easier by hand in tight or frequently accessed installations.

Q4: How is the pin secured once installed?

All CL250 models use a Φ4 open retaining ring to lock the hinge pin in place during normal use. The pin can be removed by hand when door removal is needed, without requiring tools.

Q5: What installation methods are supported?

The CL250 hinge can be installed by screw mounting or welding, depending on your cabinet fabrication method. Mounting hole configurations vary by model — refer to the dimension drawings for slot size and spacing details.

Q6: What materials are available?

The CL250 hinge comes in zinc-plated carbon steel and 304 stainless steel. Carbon steel suits indoor, dry environments; 304 stainless steel is the right choice for outdoor enclosures, high-humidity spaces, or corrosive industrial environments.
