Core Product Features & Advantages
2.1 Detachable Lift-off Barrel Structure for Tool-Free Door Removal
The unique separable barrel design with removable pin allows the entire cabinet door to be lifted off and completely detached in seconds without loosening any screws or using tools. This dramatically improves efficiency during cabinet transportation, on-site assembly, internal wiring inspection, component replacement and routine maintenance work, while the clean barrel profile provides a neat and professional appearance.
2.2 High-Strength Die-Cast Zinc Alloy with Sand Spray Chrome Plating
One-piece high-pressure zinc alloy die casting delivers excellent structural rigidity and reliable load-bearing capacity. The sand spray chrome plating forms a dense, scratch-resistant protective layer with a refined satin metallic finish, effectively resisting oxidation, fingerprints and surface abrasion, presenting a premium industrial appearance on equipment casings.
2.3 White Zinc Plated Steel Pivot Pin for Durable Rotation
The solid steel pivot pin treated with white zinc plating enhances corrosion resistance and friction durability. Precisely controlled assembly clearance within the Φ14 barrel maintains smooth wobble-free rotation over tens of thousands of open-close cycles, preventing hinge play, gap enlargement and door sagging.
2.4 Controlled 120° Opening Angle
The 120-degree maximum opening angle is engineered to provide sufficient access for internal operations while preventing the door from over-rotating and colliding with adjacent equipment, walls or operators. This controlled opening range is ideal for standard electrical cabinets and industrial equipment enclosures where full 180° opening is not required or may cause interference.
2.5 Secure Two-Point Screw Mounting
The mounting plate features 2×Φ7 through holes with 40mm center spacing, allowing M6 or M7 screws to securely fasten the hinge to the cabinet frame. The compact 55mm mounting plate with 14mm height fits neatly on standard cabinet door frames, providing stable and reliable fixation.
2.6 Compact Profile for Versatile Installation
With a 60mm overall length, Φ14 barrel diameter and compact side profile (22.5mm × 15.5mm), this hinge is suitable for a wide range of small and medium-sized equipment enclosures. The >4mm clearance and 10mm internal depth accommodate standard sheet metal door and frame configurations.
Application Fields
- Electrical control cabinets, low-voltage distribution boxes, frequency converter enclosures and PLC equipment housings
- Automation equipment protective doors, industrial test bench casings and machinery access panels
- Communication equipment cabinets, indoor server boxes and signal transfer enclosures
- Sheet metal tool cabinets, instrument test equipment casings and industrial console doors
- Medical equipment housings, laboratory analytical instruments and environmental monitoring control boxes
- Aluminum profile industrial frames, mechanical equipment maintenance hatches and test fixtures
- Applications requiring quick door removal for maintenance and a clean barrel hinge appearance
Installation & Maintenance Guidelines
Step-by-Step Installation Procedures
- Determine the installation positions on the cabinet frame according to the dimension drawing
- Mark and drill 2×Φ7 through holes at 40mm center spacing on the cabinet frame
- Align the CL246-1 hinge mounting plate against the cabinet frame and fasten with M6 or M7 screws
- Install the corresponding hinge half on the door panel (if applicable)
- Insert the white zinc plated steel pivot pin into the Φ14 barrel to connect the two halves
- Test the 120° opening movement for smooth rotation and verify the lift-off detachment function by removing the pin
- Confirm that the door closes properly and operates within the >4mm clearance specification
Installation Quantity Recommendation
- Door height ≤600mm: Install 2 hinges symmetrically
- Door height 600mm to 1000mm or medium-weight steel door: Install 3 hinges for balanced load distribution
Maintenance Instructions
- Suitable for indoor dry environments; not recommended for long-term outdoor exposure, high-humidity areas, coastal salt spray or severe chemical vapor conditions
- Wipe the sand spray chrome plated and white zinc plated surfaces periodically with a soft dry cloth to remove dust, grease and moisture
- Apply a small amount of dry lubricant to the steel pivot pin and Φ14 barrel interior every six months to maintain smooth rotation and easy lift-off
- Check mounting screw tightness quarterly to prevent loosening from vibration
- Inspect the chrome plating annually for chips or scratches; touch up with matching paint if necessary to maintain corrosion protection
