Core Product Features & Advantages

2.1 Full SUS304 Stainless Steel Construction for Superior Corrosion Resistance

The entire hinge, including both male and female halves and the pivot pin, is fabricated from premium SUS304 stainless steel, providing excellent resistance to rust, oxidation, moisture, salt spray and weak acid/alkali corrosion. Combined with the beige powder coating, it delivers double-layer protection for long-term reliable performance in outdoor, coastal and mildly corrosive industrial environments.

2.2 Detachable Male-Female Split Structure for Tool-Free Door Removal

The unique separable male-female design 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.

2.3 180° Full Flat Opening Angle

The 180-degree maximum opening angle enables the cabinet door to lay completely flat against the cabinet side panel, eliminating operational blind zones and providing full unobstructed access for internal wiring, component replacement, equipment inspection and routine maintenance work.

2.4 Beige Powder Coating for Durable Aesthetic Finish

The beige powder coating forms a uniform, UV-stable protective layer that resists scratches, chipping and fading. The light beige color offers a clean, neutral appearance that blends well with various equipment enclosure colors, making it suitable for visible exterior mounting on premium and outdoor equipment.

2.5 Dual Independent Mounting Hole Patterns

The female hinge features 2×Φ3.2 mounting holes with 15mm center spacing, while the male hinge has 2×Φ4.5 holes with 16.5mm center spacing. This independent hole configuration allows flexible alignment on both the door panel and cabinet frame, accommodating various sheet metal thicknesses and installation layouts.

2.6 Compact Size for Space-Constrained Enclosures

With an overall length of only 48mm and a compact installation footprint (9mm width, 18mm total height), this hinge is ideal for small and medium-sized equipment enclosures where installation space is limited. It fits neatly on narrow door frames and compact instrument housings without interfering with internal components.

Application Fields

Outdoor electrical distribution cabinets, waterproof power control boxes and PLC equipment enclosures
Communication base station cabinets, outdoor server boxes and signal transfer enclosures
Energy storage battery cabinets, solar inverter housings and renewable energy equipment
Coastal and marine equipment enclosures, port machinery control boxes and offshore instrument housings
Food processing equipment, stainless steel sanitary cabinets and cleanroom facility enclosures
Laboratory testing instruments, medical equipment casings and environmental monitoring devices
Outdoor monitoring equipment, traffic signal control boxes and weather-resistant instrument panels

Installation & Maintenance Guidelines

Step-by-Step Installation Procedures

Determine the installation positions on both the cabinet door panel and the frame according to the dimension drawing
On the door panel: mark and drill 2×Φ3.2 holes with 15mm center spacing for the female hinge, then fasten with M3 screws
On the cabinet frame: mark and drill 2×Φ4.5 holes with 16.5mm center spacing for the male hinge, then fasten with M4 screws
Align the male hinge pin with the female hinge socket, then lower the door panel to engage the two halves
Test the 180° opening movement for smooth rotation and verify the lift-off detachment function
Confirm that the door panel (2mm) and frame (14mm depth) fit within the specified installation dimensions

Installation Quantity Recommendation

Door height ≤400mm: Install 2 hinges symmetrically
Door height 400mm to 700mm: Install 3 hinges for balanced load distribution

Maintenance Instructions

Suitable for both indoor and outdoor environments, including damp, coastal and mildly corrosive conditions; for extreme chemical environments, regular inspection is recommended
Wipe the beige powder coated surface periodically with a soft damp cloth to remove dust, salt residue and grease
Apply a small amount of stainless steel-compatible dry lubricant to the Φ4 pivot pin and male-female engagement area every six months to maintain smooth rotation and easy lift-off
Check mounting screw tightness quarterly to prevent loosening from vibration
Inspect the powder coating annually for chips or scratches; touch up with matching paint if necessary to maintain corrosion protection
