Euro Profile V10 Cylinder & Turn 45/35mm – Keyed to Differ

In the professional security industry, a 35mm total length cylinder is a specialized component typically used in “half-cylinder” applications or very thin door profiles where a standard 60mm cylinder would protrude excessively. The 35mm Cylinder and Turn configuration is the definitive choice for modern safety; by replacing the internal keyhole with a permanent, ergonomic turn-knob, you ensure that the door can always be opened from the inside—a critical requirement for meeting fire safety and building regulations.

Despite its compact size, these 35mm Cylinder and Turn incorporate anti-pick and anti-drill technology. Hardened steel pins are strategically placed to protect the shear line, providing a formidable deterrent against common forced-entry methods while maintaining a smooth, “vault-like” mechanical action for the user.

Why the 35mm Thumbturn is the Professional Choice

• Ultra-Compact Profile: Specifically designed for narrow-style doors or situations where one side of the cylinder needs to be near-flush with the door face.

• Emergency Egress Convenience: The internal thumbturn allows for “keyless” exit, ensuring occupants are never locked inside during an emergency.

• Advanced Anti-Pick Protection: Utilizes specialized internal pins designed to catch and frustrate picking tools, significantly increasing the time required for unauthorized entry.

• Hardened Anti-Drill Defenses: Features strategically placed hardened steel pins within the cylinder body to protect the internal core from high-speed drill bits.

• Corrosion-Resistant Finishes: Available in Satin Nickel, Polished Brass, or Chrome, ensuring the internal springs remain fluid even in high-traffic environments.

• Keyed to Differ (KTD) Security: Each 35mm Cylinder and Turn is supplied with a unique key code, providing individual security for every installation.

Professional Installation and Maintenance Tips

To ensure your 35mm Cylinder and Turn operates with precision for years, follow these essential guidelines:

1. Verify Your Offset: Because 35mm is an unusual size, verify if your door requires a 10/25mm or 5/30mm split. The “turn” side must be on the interior to ensure safety.

2. Avoid Excessive Protrusion: The external face should not protrude more than 3mm from the handle or escutcheon. Excessive protrusion makes the lock vulnerable to “lock snapping” techniques.

3. Alignment is Key: When inserting the cylinder into the mortice lock, slightly rotate the thumbturn to align the internal black “cam” with the cylinder body. This allows it to slide into place without force.

4. Dry Lubrication Only: Never use WD-40 or heavy oils. These attract dust which will eventually seize the high-precision pins. Use a dedicated Graphite Powder or dry PTFE-based lock lubricant once a year.

5. Fixing Bolt Precision: Ensure the M5 fixing bolt is threaded carefully into the center of the cylinder. If it feels tight, do not force it; realign the cylinder until the bolt glides in.
