Core Product Features & Advantages

1 Lift-off Detachable Two-Piece Structure for Tool-Free Door Removal

The separable lift-off design allows the entire cabinet door to be lifted vertically 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 Premium Bright Chrome Plating for High-End Aesthetic Appearance

The mirror-polished bright chrome plating creates a highly reflective, sleek metallic finish that elevates the visual quality of any equipment enclosure. In addition to its premium appearance, the chrome plating provides a dense protective layer that effectively resists oxidation, fingerprints, surface abrasion and minor corrosion, maintaining a polished and professional look over years of service.

3 Φ8 Thickened Barrel Pivot for Robust Load-Bearing Capacity

The Φ8 oversized barrel pivot provides exceptional structural rigidity and load-bearing strength, reliably supporting medium to heavy cabinet doors without bending, sagging or deformation under long-term frequent opening and closing. The precision-machined barrel ensures tight assembly clearance and smooth, wobble-free rotation over tens of thousands of open-close cycles.

4 Secure Two-Point Screw Mounting

The mounting plate features 2×Φ6 through holes with 55mm center spacing, allowing M6 screws to securely fasten the hinge to the cabinet frame. The compact 16mm base width and 6mm thickness provide a stable mounting foundation, resisting loosening from vibration and mechanical impact.

5 Compact Low-Profile Design

With an 84mm overall length, 21mm side height and 19.5mm top width, this hinge maintains a compact profile suitable for a wide range of small and medium-sized equipment enclosures. The 7.8mm internal depth and 5mm clearance accommodate standard sheet metal door and frame configurations.

6 Versatile Application Across Industrial and Furniture Uses

The combination of durable steel construction, premium chrome finish and practical lift-off functionality makes this hinge equally suitable for industrial electrical cabinets and high-end furniture applications where both reliable performance and polished appearance are required.

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×Φ6 through holes at 55mm center spacing on the cabinet frame
Align the CL250-9 hinge mounting plate against the cabinet frame and fasten with M6 screws
Install the corresponding hinge half on the door panel (if applicable)
Align the two halves vertically and lower the door to engage the lift-off barrel
Test the opening movement for smooth rotation and verify the lift-off detachment function
Confirm that the door closes properly and lifts off smoothly without binding

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 bright chrome plated surface periodically with a soft dry or slightly damp microfiber cloth to remove dust, fingerprints and grease; avoid abrasive cleaners or scouring pads that may scratch the mirror finish
Apply a small amount of dry lubricant to the Φ8 barrel pivot and pin 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; avoid using harsh chemicals that may damage the plating
