Two Model Breakdown

1. CL204-3A Material: SUS304 Stainless Steel Application: Outdoor, coastal, damp, corrosive, high hygiene demanding environments
2. CL204-3C Material: Die-cast Zinc Alloy Application: Dry indoor general electrical cabinets, cost-sensitive mass projects

Core Product Features

2.1 Two Material Grades for Tiered Budget & Environment

• CL204-3A SUS304 Stainless Steel: Excellent rust, salt fog, acid and alkali resistance, long service life in harsh outdoor and wet workshops, ideal for food machinery, marine equipment, chemical anti-corrosion boxes.
• CL204-3C Zinc Alloy: High rigidity die-cast body, stable load performance for indoor dry scenarios, greatly reduces procurement cost for standard control cabinets and instrument housings.

2.2 Premium Mirror Bright Chrome Surface Treatment

Mirror bright chrome electroplating finish on both versions:

• Smooth, fingerprint-resistant, anti-tarnish and easy to wipe clean;
• High-gloss metallic look upgrades the aesthetic grade of automation equipment, test boxes and switch cabinets;
• Firm plating layer with strong adhesion, not easy to peel under normal use.

2.3 Tool-Free Vertical Lift-Off Quick Disassembly

Split central pin design allows direct upward lifting of the door to separate two hinge halves without any tools. Greatly accelerates internal wiring overhaul, component replacement, equipment maintenance and cabinet deep cleaning work.

2.4 Four-Point Concealed M6 Threaded Mounting

Four M6 blind threaded holes realize four-point uniform stress bearing:

• Effectively prevents heavy door sagging, hinge deformation and loose screws after long-term frequent use;
• All fasteners are hidden inside the cabinet panel, keeping the outer surface flat and neat.

2.5 Universal Non-Directional Design

Single model fits both left-opening and right-opening cabinet doors, simplifies inventory management, cuts SKU quantity and avoids assembly direction errors on site.

2.6 180° Full Unobstructed Opening

180° rotation lays the door flush against the cabinet side plate, fully exposing internal electrical modules and wiring terminals, providing maximum operating space for inspection, debugging and circuit modification.

H2 3. Application Scenarios

CL204-3A (SUS304 Stainless Steel)

1. Outdoor distribution boxes, coastal salt fog equipment, marine ship cabinets
2. Food processing machinery, medical devices, pharmaceutical sanitary enclosures
3. Water treatment equipment, chemical workshop anti-corrosion protective housings
4. High humidity factory workshops, outdoor automation control boxes

CL204-3C (Zinc Alloy)

1. Indoor low-voltage PLC control cabinets, electrical switch boxes
2. Laboratory testing instruments, desktop equipment protective covers
3. Network weak current cabinets, server indoor racks
4. General mechanical equipment enclosures with dry indoor working conditions

Selection & Installation Guide

1. Model Selection Rule Pick CL204-3A SUS304 for outdoor, damp, corrosive, washable and hygienic environments; choose CL204-3C zinc alloy for dry indoor cost-saving projects.
2. Installation Suggestion Install two hinges symmetrically if door width exceeds 550mm to share load and avoid bending. Use standard M6 socket head cap screws for concealed assembly.
3. Maintenance Tips Wipe chrome surface regularly to retain luster; add a small amount of anti-rust lubricant to the split pivot to ensure smooth lifting movement.

Product Summary
