Core Product Features & Advantages

1 Premium SUS304 Stainless Steel Construction

The entire hinge is fabricated from SUS304 stainless steel, providing excellent corrosion resistance, oxidation resistance and structural durability. Suitable for both indoor and outdoor environments, including damp, coastal and mildly corrosive conditions, it maintains reliable performance over years of service without rusting or degrading.

2 Mirror Polished Finish for High-End Aesthetic Appearance

The precision mirror polishing creates a highly reflective, sleek metallic surface that elevates the visual quality of any equipment enclosure. In addition to its premium appearance, the polished surface resists fingerprints, is easy to clean and provides an extra layer of corrosion protection, making it ideal for medical, laboratory, food processing and cleanroom applications where hygiene and appearance are critical.

3 Lift-Off Detachable Design for Quick Tool-Free Door Removal

The innovative lift-off design enables quick, tool-free door removal and installation. The door-mounted half simply lifts vertically off the fixed frame-mounted pivot pin, allowing complete door removal for unobstructed access to cabinet interiors during maintenance, component replacement or equipment installation. This dramatically reduces servicing time and improves operational efficiency.

4 Three H Offset Variants for Different Door Configurations

The hinge is available in three carefully calibrated variants to accommodate different door panel offsets and cabinet construction standards: CL268-1 (H=23.5mm) for larger door offsets, CL268-2 (H=20.5mm) for medium door offsets, and CL268-3 (H=17.5mm) for smaller door offsets. This ensures proper fit, optimal pivot alignment and smooth operation regardless of the cabinet door-frame configuration.

5 Long 126mm Body with Four-Point M5 Mounting

The substantial 126mm overall length provides broad load distribution across the cabinet door, effectively resisting sagging and deformation under heavy door weight. The 4×Φ5.4 mounting holes (2 on the main body, 2 on the side brackets) allow M5 screws to securely fasten both hinge halves to the frame and door, providing robust and stable installation.

6 180° Full Opening with Φ6 Precision Pivot Pin

The 180-degree maximum opening angle enables the cabinet door to lay completely flat, eliminating operational blind zones and providing full unobstructed access for internal wiring, component replacement and routine maintenance. The Φ6 precision-machined pivot pin ensures tight clearance, low-friction rotation and minimal wobble, delivering smooth and quiet operation over tens of thousands of open-close cycles.

Application Fields

Outdoor monitoring equipment, weather-resistant instrument panels and coastal equipment enclosures
Marine and boat equipment, RV accessories and outdoor fixtures requiring corrosion-resistant stainless steel hardware
Premium furniture, electronic equipment casings and decorative enclosures where polished appearance is preferred
Sheet metal tool cabinets, industrial console doors and storage enclosures requiring frequent door removal
Applications where lift-off detachable functionality and corrosion-resistant polished hardware are required

Installation & Maintenance Guidelines

Step-by-Step Installation Procedures

Select the appropriate H variant based on door panel offset: CL268-1 (H=23.5), CL268-2 (H=20.5) or CL268-3 (H=17.5)
Determine the installation positions on both the cabinet frame and door panel according to the dimension drawing
On the cabinet frame: mark and drill 2×Φ5.4 through holes for the frame-mounted hinge half (side brackets, 100.3mm outer spacing)
On the door panel: mark and drill 2×Φ5.4 through holes for the door-mounted hinge half (main body, 48mm center / 67.8mm outer spacing)
Fasten the frame-mounted half to the cabinet frame with M5 screws through the 2 side bracket holes
Fasten the door-mounted half to the door panel with M5 screws through the 2 main body holes
Align the door-mounted half over the frame-mounted pivot pin and lower the door into place
Verify that the pivot pin is fully engaged and that the door lifts off smoothly
Test the 180° opening movement for smooth rotation and verify hinge stability
Adjust the mounting position slightly if needed to achieve proper door alignment and consistent gap spacing

Installation Quantity Recommendation

Door height ≤800mm: Install 2 lift-off hinges symmetrically (top and bottom)
Door height 800mm to 1500mm or heavy steel door: Install 3 hinges (top, middle, bottom) for balanced load distribution
Note: For proper lift-off operation, all hinges on a door should be vertically aligned to ensure synchronized pin engagement

Maintenance Instructions

Suitable for both indoor and outdoor environments, including damp, coastal and mildly corrosive conditions; for extreme salt spray or strong chemical environments, regular rinsing with fresh water is recommended
Wipe the mirror polished 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 Φ6 pivot pin every six months to maintain smooth and quiet rotation
Check all 4 M5 mounting screw tightness quarterly to prevent loosening from vibration
Inspect the polished surface annually for scratches or corrosion; for coastal applications, rinse with fresh water periodically to remove salt deposits
Test the lift-off operation annually to verify smooth pin engagement and door removal; clean the pivot pin if any debris accumulates
Verify that the H variant remains appropriate for the door offset; if cabinet modifications change the offset, switch to the appropriate CL268 variant
