Euro Profile V10 Single Cylinder 42mm – Master Keyed (MK1)

42mm V10 Euro Single Cylinder Master Keyed (MK1) is the professional’s benchmark for one-sided, high-security access control. In the world of architectural ironmongery, the V10 series is synonymous with precision engineering, designed to offer a superior defense against sophisticated bypass techniques while providing the mechanical flexibility required for Master Keyed (MK1) systems in commercial and industrial environments.

By integrating a dual-row, 10-pin system into a compact “Half Cylinder” format, the 42mm V10 Euro Single Cylinder Master Keyed provides a tamper-proof “blind” internal face and a highly complex internal architecture that allows for thousands of secure key combinations.

The “V10” designation refers to the internal 10-pin dual-row mechanism. This high pin count is a critical requirement for Master Keying, as it provides the mathematical “differs” necessary to create a secure hierarchy without “ghost keys” (unintended keys opening the lock).

Key Performance Benefits

• Tiered Access Hierarchy (MK1): This 42mm V10 Euro Single Cylinder Master Keyed is specifically pinned to recognize both a Change Key (for daily users) and a Master Key (for facility managers). This allows for a “one-key” solution across a multi-door facility, reducing the weight and complexity of staff key bundles.

• Pick & Bump Immunity: The dual-row configuration of hardened steel pins creates a significantly more complex shear line. This makes the V10 virtually immune to traditional picking and kinetic “bumping” techniques often used on standard 6-pin locks.

• Restricted Key Control: V10 cylinders are supplied with a unique security code card. This ensures that duplicate keys cannot be cut at a high-street locksmith without proof of authorization, giving facility managers total control over who possesses a key to the premises.

• Hardened Drill Defense: The cylinder face is reinforced with high-density hardened steel pins and a ceramic internal plate. This system is designed to shatter or dull high-speed drill bits, protecting the pin stacks from destructive entry.

Precision Sizing: The 32/10 Asymmetric Split

A 42mm single cylinder is measured from the center of the fixing screw to each end. In this configuration, the 32mm external reach is optimized for modern building materials that require a flush, secure fit.

Architectural Tip: The 32mm external offset is specifically tailored for slimline aluminum shopfronts and narrow-profile doors. It ensures the cylinder sits flush with the handle escutcheon, eliminating the “shoulder” protrusion that burglars use to grip and snap a lock.

Recommended Access Solutions

For commercial facility managers or high-end residential projects, 42mm V10 Euro Single Cylinder Master Keyed is the definitive choice. Its ability to be integrated into complex MK1 systems means you can manage a whole block of shutters, gates, and panic exits with a single, high-security master key. V10 42mm Single Cylinder (MK1)

Installation Pro-Tip: The “8-Position” Universal Cam

One of the most valuable features of the 42mm V10 Euro Single Cylinder Master Keyed is its adjustable cam. Because different brands of panic bars and shutter locks require the internal actuator (the cam) to sit at different starting angles, the V10 is designed for universal compatibility.

1. Locate the small spring-loaded pin on the side of the cylinder body.

2. Depress the pin and manually rotate the cam to the desired angle (typically 30° or 45°).

3. Release the pin to lock the cam into position. This ensures that the key can be inserted and turned without the cam “binding” against the internal stops of the lock case.

Enhance your security system with the 42mm V10 Euro Single Cylinder Master Keyed, designed for smooth operation and efficient access control. This cylinder allows the use of a master key to open multiple locks while maintaining independent keys for individual cylinders. The 42mm Euro profile ensures a precise and secure fit for standard doors, making it ideal for homes, offices, and multi-unit properties.

Crafted from durable, high-quality materials, the 42mm V10 Euro Single Cylinder Master Keyed provides strong resistance to tampering, forced entry, and daily wear.
