The 40mm V10 Euro Double Cylinder is a high-specification security component engineered for specialized door profiles where space is at a premium. Measuring just 40mm in total length, this 40mm V10 Euro Double Cylinder features a unique 30/10mm offset, making it the essential solution for narrow-stile aluminum doors, slimline shopfronts, and modern glazed partitions.

As a Double Cylinder (Key/Key operation), it provides a high-security solution for doors with glass vision panels. By requiring a key for operation from both the interior and exterior, it eliminates the vulnerability of a thumbturn that could be manipulated by an intruder through broken glass.

Technical Specifications of 40mm V10 Euro Double Cylinder

The V10 series is defined by its precision-engineered 10-pin internal mechanism, offering a significant security upgrade over standard 5 or 6-pin domestic cylinders.

High-Security Engineering & Protection

10-Pin Anti-Pick Technology: By utilizing a high-density pin configuration, the V10 makes manual picking nearly impossible. The sheer number of combinations ensures maximum resistance against sophisticated picking tools.
Hardened Anti-Drill Defenses: The cylinder body and core are reinforced with hardened steel pins and plates. These are strategically positioned to deflect drill bits and protect the internal springs from destructive entry techniques.
Anti-Snap Sacrificial Line: Despite its compact size, the V10 features a sacrificial “snap line.” In the event of an attack, the cylinder breaks in a way that keeps the central locking cam secure and inaccessible.
Corrosion Resistance: The high-quality plating ensures that the internal 10-pin mechanism remains operational even in high-moisture environments or coastal locations.

Strategic Applications

Narrow-Stile Aluminum Doors: Perfect for the slim frames found on modern patio doors or commercial shopfronts where internal depth is limited.
Glazed “Vision” Panels: Because this is a Double Cylinder, it is the safest choice for doors with glass panes, preventing “reach-through” bypasses.
Thin Timber Partitions: Ideal for internal office doors or server rooms where a compact, high-security lock is required to fit into minimalist designer hardware.

Professional Installation Tip: The “Short” Side Orientation

The 40mm V10 Euro Double Cylinder is highly asymmetrical (30/10mm).

Orientation: The 10mm side is exceptionally short and is designed to sit nearly flush with the lock face or a very thin escutcheon on the “thin” side of the door profile.
Flush Fit: For maximum security, the exterior face of the cylinder should not protrude more than 3mm from the door handle or protective escutcheon. Any more than this makes the lock a target for “cylinder snapping” tools.
Lubrication: To maintain the precision of the 10-pin system, use a dry graphite lubricant once a year. Never use oil-based lubricants (like WD-40), as they can attract dust and clog the high-security pins.

Enhance your property’s protection with the 40mm V10 Euro Double Cylinder , a secure and practical solution for doors in both residential and commercial settings. Designed with precision, this cylinder lock ensures smooth key operation while providing dependable resistance against forced entry. The 35/40mm sizing makes it suitable for a variety of standard doors, offering an excellent balance of security and functionality.

Crafted from high-quality materials, the 40mm V10 Euro Double Cylinder delivers long-lasting durability and everyday reliability. Its keyed-to-differ feature means each lock operates with its own unique key, ideal for multi-unit buildings, offices, or properties where independent access is required. Easy to fit and built for performance, this 40mm V10 Euro Double Cylinder provides strength, convenience, and peace of mind for your security needs.
