Two Model Classification

1. CL204-3B Material: High-pressure die-cast Zinc Alloy Application: Dry indoor cabinets, cost-sensitive standard equipment with offset installation requirement
2. CL204-3BS Material: SUS304 Stainless Steel Application: Outdoor, coastal, damp, corrosive, washable and sanitary working environments

Core Product Features

2.1 Exclusive 3mm Offset Step Design (Core Difference)

The 3mm stepped offset solves the installation problem of two uneven cabinet panels. It realizes flush closing when the door frame and door plate have thickness difference, avoids protruding gaps, keeps the cabinet exterior neat and sealed, which ordinary flat lift-off hinges cannot achieve.

2.2 Dual Material Graded Selection

• CL204-3BS SUS304 Stainless Steel: Outstanding anti-rust, salt spray and corrosion resistance, long service life in humid workshops, outdoor distribution boxes, food machinery and marine equipment.
• CL204-3B Zinc Alloy: Integrated die-casting with strong rigidity and stable load-bearing performance, economical choice for mass indoor electrical control cabinets, instrument boxes and mechanical protective covers.

2.3 High-Gloss Mirror Bright Chrome Surface

Mirror electroplated chrome layer is smooth, anti-fingerprint, anti-tarnish and easy to clean. The high reflective metallic texture greatly upgrades the visual grade of automation equipment, test enclosures and switch cabinets with strict appearance standards.

2.4 Tool-Free Vertical Lift-Off Disassembly

Split central pin structure enables quick separation by lifting the cabinet door straight upward without any tools. Greatly improves efficiency for internal wiring maintenance, module replacement, cabinet overhaul and deep cleaning.

2.5 Four-Point M6 Concealed Mounting

Four M6 threaded holes form four-point uniform force bearing, effectively prevent door sagging, hinge deformation and screw loosening after long-term frequent opening and closing. All fasteners are hidden inside the panel to maintain a flat outer surface.

2.6 Universal Non-Directional Structure

One single part fits both left-opening and right-opening doors, reduces inventory SKU quantity and eliminates on-site assembly direction errors. 180° full opening provides maximum operation space for internal inspection and circuit debugging.

Application Scenarios

CL204-3BS (SUS304 Stainless Steel Version)

1. Outdoor offset installation distribution boxes, coastal salt fog anti-corrosion equipment
2. Food and beverage processing machinery, medical and pharmaceutical sanitary cabinets
3. Water treatment equipment, chemical workshop protective housings, high humidity factory enclosures

CL204-3B (Zinc Alloy Version)

1. Indoor PLC control cabinets, electrical switch boxes with unequal panel thickness
2. Laboratory testing instruments, desktop equipment offset protective covers
3. Indoor network cabinets, general mechanical equipment enclosures in dry environment

Selection & Installation Guide

1. Model Selection Rule Choose CL204-3BS SUS304 for outdoor, damp, corrosive or hygienic scenarios; select CL204-3B zinc alloy for dry indoor cost-saving offset installation projects.
2. Installation Tips Install two hinges symmetrically if door width exceeds 550mm to share load. Use standard M6 socket head cap screws for concealed assembly, align the 3mm step with the panel thickness difference during mounting.
3. Maintenance Wipe the chrome surface regularly to keep luster; add a small amount of anti-rust lubricant to the split pivot for smooth lifting movement.

Product Summary

CL204-3B and CL204-3BS are offset stepped upgraded models of the CL204 series lift-off hinges, with identical overall dimensions and 4-M6 mounting holes. The 3mm offset step perfectly adapts to uneven cabinet panel assembly. Two material options cover economical indoor use (zinc alloy CL204-3B) and harsh environment anti-corrosion demand (SUS304 CL204-3BS). Equipped with mirror chrome high-end finish and tool-free separable structure, it is a professional detachable hinge solution for cabinets with special staggered installation requirements.
