Euro Profile V10 Double Cylinder 100mm – Keyed to Differ

At 100mm in total length, this 100mm euro profile double cylinder is a high-capacity hardware solution. Standard 60mm–70mm barrels are simply too short for high-performance doors; the 100mm length ensures the key-way remains flush with the handle furniture for easy operation.

Why 100mm? Applications for Oversized Doors

• High-Performance Fire Doors: FD90 and FD120 timber doors are significantly thicker than standard doors to meet extreme heat-resistance ratings. A 100mm euro profile double cylinder provides the necessary “reach” to clear these heavy leaves.

• Armored & Ballistic Entrances: Banks, data centers, and government buildings use reinforced steel doors. The 100mm euro profile double cylinder is often required to pass through internal steel plating and external anti-drill shielding.

• Modern Architectural Composite Doors: High-end residential doors with deep decorative moldings or “shaker” style cladding often require a longer barrel to ensure the key is easy to insert.

Key Security Benefits

• Double-Sided Deadlocking: Unlike a thumbturn, a 100mm euro profile double cylinder requires a key for both entry and exit. This is a critical anti-theft feature for retail stores and warehouses where “internal” security is just as important as the external perimeter.

• Shatter-Point Security: If your door features a glass side-light, an intruder cannot simply smash the glass and turn a knob. The internal key-way keeps the door deadlocked.

• Anti-Snap Engineering: Premium 100mm euro profile double cylinder feature a “sacrificial snap line.” If an attacker attempts to “snap” the lock with heavy-duty tools, the barrel breaks at a predetermined point, leaving the central cam locked and the internal mechanism shielded.

Precision Sizing: Getting the 100mm Offset Right

Because a 100mm euro profile double cylinder is significantly longer than average, choosing the correct offset is vital for both security and aesthetics. Euro cylinders are measured from the center of the fixing screw hole to each end of the barrel ($A + B = 100mm$).

1. 50/50 (Symmetric): The fixing hole is exactly in the center. This is the standard for 74mm–84mm timber doors where the mortice lock is installed dead-center.

2. 45/55 or 40/60 (Asymmetric): Often required for modern composite or reinforced steel doors where the external face is thicker due to decorative cladding or ballistic plating, shifting the locking point off-center.

Pro-Tip: For maximum security, the cylinder should never protrude more than 3mm from the face of the handle. Any protrusion beyond this provides an easy “purchase” point for lock-snapping tools.

For a robust, professional-grade solution for commercial secondary entry points or high-traffic fire exits, the ERA 6-Pin Euro Cylinder offers exceptional durability. It features multiple hardened steel anti-drill pins and a 6-pin “mushroom” driver system that makes picking nearly impossible for standard intruders.

Maintenance for Longevity

To keep your 100mm euro profile double cylinder operating smoothly, never use oil or WD-40, as these attract dust that can jam the delicate internal springs. Instead, use a dry graphite lubricant or a specialized PTFE lock spray once a year to ensure the key slides in and turns with zero resistance.
