The 72mm Euro Cylinder and Turn is a high-performance security solution designed for those who demand uncompromising safety without sacrificing daily convenience. This 72mm cylinder is engineered with an offset profile (40mm / 32mm), making it a versatile choice for a wide range of modern timber, composite, and uPVC doors.

Featuring a “Thumbturn” interior, this 72mm Euro Cylinder and Turn allows for instant, keyless operation from the inside—perfect for high-traffic homes and critical fire escape routes—while maintaining a high-security, keyed entry on the exterior. The V10 series is synonymous with precision engineering, offering advanced protection against the most common methods of forced entry.

High-Security Engineering & Protection Features

The “V10” designation refers to the sophisticated internal pin system, which provides a significantly higher level of security than standard domestic cylinders.

10-Pin Anti-Pick Technology: While standard locks use 5 or 6 pins, the V10 utilizes an advanced 10-pin system. These precision-machined pins are designed with varying shapes and heights to thwart even the most experienced picking attempts.
Anti-Drill Defenses: The cylinder body and core are reinforced with hardened steel pins and plates. These “anti-drill” zones are strategically placed to deflect drill bits and protect the internal mechanism from destructive bypass techniques.
Anti-Bump & Anti-Snap Construction: Engineered to resist “lock bumping,” the 72mm Euro Cylinder and Turn features specialized driver pins that remain stable under kinetic impact. Additionally, the sacrificial “snap line” ensures that if the lock is attacked, it breaks in a way that keeps the central locking cam secure and inaccessible.
Smooth Thumbturn Operation: The interior turn is ergonomically designed for a comfortable grip. It provides smooth, mechanical feedback, ensuring that locking your home at night is an effortless, one-handed task.

Critical Application & Safety Benefits

Choosing a “Cylinder and Turn” configuration provides specific advantages for modern living and commercial safety standards:

Fire Safety & Rapid Exit: In the event of a fire, every second counts. A 72mm Euro Cylinder and Turn ensures that occupants can unlock the door and exit the building instantly without searching for a key. This makes it the standard requirement for primary exit doors and rental properties.
The “Offset” Advantage: The 40/32mm split is specifically designed for doors where the lock case is not perfectly centered. This is common in doors with thick external decorative panels or specific multi-point locking strips.
Keyed to Differ (KTD) Security: “Keyed to Differ” means your lock is unique. Unlike “Keyed Alike” sets, this ensures that no other key in the V10 production line will operate your door, providing maximum individual security for residential front doors.
Architectural Integration: The V10 series is designed to fit seamlessly into standard Euro-profile cut-outs, making it an ideal upgrade for existing handles and escutcheons.

Professional Installation Guide: The “Center-Screw” Alignment

Because this is an offset cylinder (40/32), correct orientation during installation is vital for both security and functionality.

Determine the Exterior: Identify which side of the door requires the 40mm length and which requires the 32mm length. Usually, the longer side (40mm) faces the exterior to account for the thickness of the handle or protective escutcheon.
The Fixing Bolt: Align the black rotating cam with the center of the cylinder. Insert the lock into the door and thread the long M5 fixing screw through the side of the door. Hand-tighten only; over-tightening can cause the cylinder to “pinch” the lock case, leading to a stiff key action.
The 3mm Security Rule: For the highest level of security, the cylinder should sit as flush as possible with your door furniture. A cylinder that protrudes more than 3mm from the handle is a target for “lock snapping” tools.
Maintenance: To keep the 10-pin system operating perfectly, apply a small amount of dry graphite lubricant to the keyway once a year. Avoid using oil or WD-40, as these can attract dust and clog the precision pins.

Enhance your door security with this 72mm Euro Cylinder and Turn – Keyed to Differ, engineered for smooth operation, strength, and long-lasting reliability. Each cylinder operates with its own unique key, making it perfect for residential, commercial, and multi-unit properties where independent access is required. The 40/32mm Euro profile size ensures a precise fit for standard doors, providing a secure and practical locking solution.

Crafted from premium materials, this 72mm Euro Cylinder and Turn resists tampering, forced entry, and daily wear. Its keyed-to-differ feature allows each cylinder to operate independently, making it ideal for apartments, offices, and multi-door installations. Easy to install and built for everyday use, this cylinder lock combines strength, convenience, and peace of mind.
