Product Overview
The 5402-100-KS is an industrial-grade long pattern latch hook that must be used with a matching strike plate to form a complete latching system. NRH has been dedicated to case hardware since 1996. This model is manufactured from premium mild steel with a yellow zinc plating finish, delivering excellent corrosion resistance and mechanical durability.
Working Principle
This latch operates on a lever and over-center mechanism. The latch hook mounts on the lid, and the strike plate mounts on the opposing case body. When pressed downward, the hook slides into the strike plate opening and generates tension. As the latch flattens completely, the mechanism passes the over-center point, creating a self-locking state where external vibration actually tightens the latch further. Lift the hook to open.
Key Features
- Material & Finish: Mild steel with yellow zinc plating - corrosion-resistant and wear-resistant, suitable for humid or industrial environments.
- High Load Capacity: Rated for 40kg - meets heavy-duty case and equipment fastening requirements.
- Vibration-Resistant & Anti-Loosening Design: Over-center self-locking mechanism effectively resists accidental opening caused by transport and mechanical vibration.
- Flexible Mounting: Base plate features three Ø4.3mm through holes and three Ø7.2mm countersunk holes, compatible with multiple screw types.
Key Dimensions
Overall length is 99mm. Mounting hole configuration: three Ø4.3mm through holes and three Ø7.2mm countersunk holes, allowing flush or standard installation.
Typical Applications
- Flight Cases: Stage, film, and aviation transport cases - vibration resistance protects sensitive equipment.
- Medical Equipment: Mobile medical carts and emergency kits - yellow zinc withstands disinfectant wiping.
- Military Cases: Ammunition boxes and communication instrument cases - meets shock resistance requirements.
- Firefighting Cases: Fire tool storage boxes - quick and reliable opening and closing.
- Heavy-Duty Luggage: Large checked luggage and tool travel cases - high load prevents accidental opening.
- Machinery & Equipment: Industrial cabinet access doors and machine guards - resists factory vibration.
