Door Cylinder ABUS D6XBK 35/35 Black — Double-Sided Euro Profile Lock Core

The ABUS D6XBK 35/35 Black is a double-sided euro profile door cylinder designed for replacement or upgrade of standard euro-profile lock cores. With symmetrical 35/35 mm segmented lengths and a black finish, this lock core provides key operation from either side and is compatible with most mortise and multipoint locking mechanisms used in residential and light commercial doors. The cylinder is intended to fit standard euro-profile escutcheons and can be used where a reversible, keyed locking solution is required.

Advantages

The ABUS D6XBK offers straightforward, reversible key operation on both sides, making it convenient for doors that require access from either direction. Its segmented 35/35 mm length provides balanced installation in standard doors without additional modification. The black finish gives a consistent, discreet appearance that matches dark hardware and modern door designs while providing the mechanical function expected from a euro cylinder.

Suitable for

• Home entrance doors with euro-profile mortise locks
• Internal doors with multipoint locking systems
• Replacement of worn or damaged euro-profile cylinders
• Light commercial doors requiring keyed access from both sides

When it may not be suitable

This double-sided cylinder is not suitable for doors where one-sided keyless egress (thumbturn) is required for safety or emergency escape. It may also be unsuitable for high-security applications that require certified anti-snap, drill-resistant or restricted-key systems beyond the standard mechanical features of a general-purpose euro cylinder.

Key specifications

• Type: Double-sided euro profile cylinder
• Overall segmented length: 35 mm / 35 mm (symmetrical)
• Finish: Black
• Operation: Keyed on both sides
• Compatibility: Standard euro-profile mortise and multipoint lock cases

How to use

Install the cylinder into a compatible euro-profile lock case by inserting it into the door’s cylinder cavity and securing it with the fixing screw through the edge of the door. Ensure the cam aligns with the lock mechanism before tightening. Use the supplied or correctly cut keys to operate the cylinder from either side; the cylinder rotates the internal cam to engage or disengage the bolt or multipoint locking components. For replacement, remove the old fixing screw, withdraw the existing cylinder, and fit the ABUS D6XBK in the same orientation and depth.

What to consider before purchase

• Confirm the required cylinder lengths (35/35 mm) match your door thickness and escutcheon positioning
• Verify your existing lock case accepts a double-sided euro profile cylinder
• Decide if a one-sided thumbturn or a higher-security certified cylinder is needed instead
• Check keying requirements: single keying, master keying, or keyed alike arrangements if applicable

Usage recommendations

For reliable operation, ensure correct alignment of the cam with your door’s lock mechanism and tighten the fixing screw to the manufacturer’s torque recommendations. Periodically lubricate the cylinder with a graphite or silicone-based lock lubricant and avoid using oil-based products. If fitting to external doors, combine with appropriate door furniture and escutcheons for weather protection and tamper resistance.
