Euro Profile V10 Double Cylinder 35/55mm – Keyed to Differ

The 90mm Euro Profile V10 Double Cylinder (specifically the 35/55mm offset) is an architectural-grade security solution designed for high-performance doors that require extended reach and maximum mechanical protection. As a Double Cylinder (Key/Key operation), it provides keyed entry and exit from both sides of the door. This configuration is a critical security requirement for doors with glass vision panels or adjacent windows, as it prevents an intruder from simply breaking the glass and reaching inside to unlock the door.

The 90mm Euro Profile V10 Double Cylinder is defined by its sophisticated 10-pin internal mechanism, offering a significant security upgrade over standard 5 or 6-pin domestic cylinders. This high-density pin array provides a formidable barrier against professional bypass techniques, making it the preferred choice for both high-end residential properties and sensitive commercial applications.

Technical Specifications of 90mm Euro Profile V10 Double Cylinder

The 90mm V10 cylinder is manufactured to exacting tolerances, ensuring smooth, reliable operation even in high-traffic environments or heavy-duty commercial doors.

High-Security Defensive Features

The V10 series integrates multiple layers of mechanical defense to protect against both “clean” picking and “destructive” forced entry methods:

• 10-Pin Anti-Pick Technology: By utilizing a multi-row, high-density pin configuration, the 90mm Euro Profile V10 Double Cylinder makes manual picking and raking nearly impossible. The sheer number of internal combinations creates a vast “key bitting” array, ensuring that only the authorized key can align the shear line.

• Hardened Anti-Drill Defenses: The cylinder face and internal core are reinforced with hardened steel pins and plates. These “anti-drill” zones are strategically positioned to deflect high-speed drill bits and protect the internal springs from destructive bypass attempts.

• Anti-Snap Sacrificial Line: In the event of a “lock snapping” attack—a common method of forced entry—the cylinder is designed to break at a predetermined sacrificial line. This leaves the central locking cam intact and protected deep within the lock case, preventing the door from being opened.

• Anti-Bump Resistance: Specialized driver pins are engineered to remain stable under the kinetic impact of “bumping” techniques, ensuring the lock remains secure against vibration-based bypasses.

Primary Applications

The 90mm (35/55) configuration is specifically designed for specialized door depths and architectural hardware:

1. Thick Timber & Composite Doors: Ideal for modern, high-performance doors that exceed the standard 44mm thickness, common in energy-efficient builds.

2. Decorative Pull Handles & Escutcheons: The 55mm offset provides the necessary length to pass through thick decorative handle plates or protective rose furniture on the exterior of the door.

3. Glazed Vision Panels: Highly recommended for any door featuring glass panes; the requirement for a key on both sides prevents “reach-through” bypasses.

4. Commercial Entrance Systems: Provides a robust, professional-grade security solution for high-traffic shopfronts and office perimeter doors.

Professional Installation Tip: Orientation & Maintenance

Because this is an asymmetrical cylinder (35/55), correct orientation is vital for both security and aesthetic appeal.

• Determine the Exterior: Measure from the center of the lock fixing screw to the outside edge of the door (including the handle plate). The 55mm side is typically used for the exterior if you have a thicker handle or a protective escutcheon.

• The 3mm Rule: For maximum protection, the exterior face of the cylinder should not protrude more than 3mm from the face of the door handle. A protruding cylinder provides a “grip point” for snapping tools.

• Dry Lubrication: To maintain the precision of the 10-pin system, apply a dry graphite lubricant to the keyway once a year. Avoid oil-based lubricants (like WD-40), as they attract dust and grit which can eventually clog the high-precision springs.
