3 Star Euro Profile Cylinder

This cylinder is specifically designed for high resistance against picking and drilling attacks rather than snap protection.

Unlike our full anti-snap 3-star cylinder series, this model does not include a reinforced anti-snap bar. Instead, the design focuses on advanced manipulation resistance and drill protection for applications where covert entry methods are more likely than forced snapping attacks.

Typical applications include premium office buildings, luxury residential projects, government facilities, and secure commercial environments.

The cylinder provides a pick resistance time of 15 minutes or more.

Testing was conducted using 10 commonly used lock manipulation tools, including bump keys, single-pin picks, and rake tools. The average opening time during testing was 16.8 minutes, exceeding the national 3-star security requirement.

The cylinder incorporates three 6mm alloy steel anti-drill pins positioned at key drilling points within the core structure.

When a drill bit contacts these hardened steel pins, the pins disrupt drilling by deflecting or jamming the bit.

Testing was performed using a 3,000 RPM drill. After 2 minutes of continuous drilling, only the surface plating was penetrated, while the internal cylinder mechanism remained operational.

The locking system uses a 7-pin configuration combined with a patented side pin mechanism.

Additional side pins are integrated along the side channel of the cylinder. Conventional picking tools typically target only the front pin stack, while the side pin system prevents rotation unless both pin systems are correctly aligned simultaneously.

This significantly increases manipulation difficulty compared with standard 7-pin cylinders.

Each 3-star euro profile cylinder is individually serialized for traceability.

Certification records can be verified through the National Lock Quality Testing Center database.

The patented side pin structure is exclusive to Wenzhong and is not commonly found in standard 3-star cylinders.

Each cylinder includes 3 standard keys, with support for up to 10 keys upon request.

Compatible with euro-profile lock bodies featuring a 72mm center distance.

Suitable for door thicknesses from 35mm to 55mm.

This 3-star euro profile cylinder is suitable for high-end office buildings, luxury residential properties, government facilities, and banking office areas requiring enhanced protection against covert entry methods.
