High Security Zinc Alloy Blade Lock with Multi-Blade Mechanism for Cabinets and Safes

Zinc Alloy Blade Lock

1. Product Overview

The Zinc Alloy Blade Lock is a compact and reliable mechanical locking solution designed for safes, cabinets, lockers, toolboxes, and electrical enclosures.
Made of high-strength zinc alloy through precision die-casting and surface electroplating, it features excellent durability, corrosion resistance, and an elegant metallic finish.
Its blade lock core structure effectively prevents technical unlocking, providing enhanced security and long service life.

2. Key Features

Durable Construction – Made of premium zinc alloy with chrome, nickel, or electrophoretic black surface finish for long-lasting performance.

High Security – Multi-blade lock core design resists prying and unauthorized access.

Smooth Operation – Key rotation is smooth and stable, ensuring easy daily use.

Customizable Options – Available in multiple shapes, finishes, and key types to fit different cabinet or safe designs.

Easy Installation – Simple panel mounting or nut-fixing design, compatible with various door panel thicknesses.

3. Working Principle

The blade lock uses a multi-blade mechanism inside the cylinder.
Each blade corresponds to a notch on the key.
When the correct key is inserted, all blades align at the shear line, allowing the cylinder to rotate and unlock.
If the wrong key is used, misaligned blades prevent rotation—ensuring anti-pick protection and high security.
