Core Product Features & Advantages

2.1 Composite Material Design, Balance Rigidity & Wear Resistance

The hinge leaf is high-pressure die-cast zinc alloy for high dimensional precision and smooth folding action; the central rotating pin is made of solid SUS304 stainless steel. The stainless steel pin greatly reduces friction loss during frequent opening and closing, avoids rust and pin seizure, extending the whole hinge service life significantly compared to full zinc alloy pins.

2.2 Bright Chrome Plating Surface for Protection & Appearance

Mirror bright chrome electroplating layer forms a tight anti-oxidation protective film on the zinc alloy surface. It resists fingerprints, slight moisture and dust corrosion indoors, with a sleek metallic look that elevates the finished grade of control cabinets, instrument housings and sheet metal equipment.

2.3 Two Independent Installation Structures for All Assembly Scenarios

• CL209-1 M6 Embedded Stud Type: Ideal for hollow cabinet frames and thin metal panels. Simply pass M6 studs through pre-drilled holes and lock with nuts from the backside, no complicated tapping required, fast for mass production line assembly.
• CL209-2 Countersunk Hole Type: Designed for surface flush mounting. Flat head screws sink completely into 90° countersinks, keeping the hinge surface flat and unobtrusive, perfect for cabinet doors that require seamless exterior.

2.4 Standard Heavy-Duty Butt Hinge Structure

Multi-leaf segmented hinge knuckle ensures uniform force distribution during rotation, effectively bearing the weight of metal cabinet doors, preventing door sagging, loose pivot and abnormal rattling after long-term repeated use. The compact 54×40mm footprint fits most standard-sized industrial enclosures.

2.5 Wide Compatibility for Standard Cabinet Panels

Symmetrical four-hole layout conforms to common cabinet hinge hole spacing standards, easy to replace old hinges on existing equipment without redesigning mounting positions, reducing customer modification cost.

Typical Application Scenarios

1. Indoor electrical control cabinets, PLC junction boxes, power distribution enclosures and switch equipment housings
2. Industrial automation devices, testing instruments, laboratory equipment protective casings
3. Network weak current cabinets, communication equipment boxes, server cabinet access panels
4. Medical indoor non-corrosive equipment casings, vending machine back doors and display device flip covers
5. Batch standardized sheet metal cabinet projects requiring two different mounting methods

Selection & Installation Guide

4.1 How to Choose the Right Model

• Pick CL209-1: If you need through-panel nut locking, hollow frames, or want quick bolt-on assembly without countersinking.
• Pick CL209-2: If flush flat surface installation is required, using flat head screws on solid flat panels.

4.2 Installation Quantity Suggestion

For door height below 600mm, install 2 hinges symmetrically; for taller or heavier metal doors, add a third hinge in the middle for load sharing.

4.3 Maintenance Instructions

Suitable for dry indoor environments only, keep away from high humidity, chemical fumes and corrosive workshops. Wipe chrome surface regularly; add a tiny amount of lubricant on the SUS304 pivot pin to maintain smooth rotation.

Product Summary
