Door cylinder ABUS E50N 30/40 – double cylinder for doors, 30 mm left / 40 mm right

ABUS E50N 30/40 is a double Euro-profile door cylinder with asymmetric lengths of 30 mm (left) and 40 mm (right). Designed for standard residential and light commercial door locks, this mechanical cylinder provides keyed operation from both sides and is compatible with locks that accept Euro-profile double cylinders. The cylinder is intended for replacing or installing in doors that require different left and right measurements, ensuring correct fit and secure mechanical operation.

Advantages

The cylinder offers straightforward mechanical key operation without electronic components, making it reliable and easy to maintain. Its asymmetric 30/40 length suits doors where one side needs a shorter projection than the other, allowing proper alignment with lock cases, handles, and escutcheons. Manufactured by ABUS, the cylinder follows common Euro-profile standards and is suitable for direct replacement of many existing cylinders of the same profile and dimensions.

Suitable for

• Residential entrance and internal doors requiring a double Euro-profile cylinder
• Light commercial premises with standard Euro-profile locks
• Replacement of worn or damaged double cylinders with asymmetric lengths
• Doors where 30 mm on one side and 40 mm on the other are required for correct alignment

Key specifications

• Type: Double Euro-profile cylinder (double cylinder)
• Length: Asymmetric 30 mm (left) / 40 mm (right)
• Operation: Mechanical key-operated from both sides
• Compatibility: Fits standard Euro-profile door lock mechanisms and escutcheons
• Intended use: Residential and light commercial doors

How to use

Measure the door thickness and existing cylinder projection to confirm that the 30/40 mm asymmetric length matches the required dimensions. To install, remove the existing cylinder by loosening the fixing screw in the lock case, align the cam and insert the new ABUS E50N cylinder until it sits flush with the escutcheon, then secure it with the fixing screw. Test key operation from both sides to ensure smooth turning and correct engagement with the locking mechanism. For replacement, ensure that the cam orientation matches the lock before tightening.

Usage recommendations

Use the ABUS E50N 30/40 in doors that specifically require asymmetric cylinder lengths to avoid misalignment. Regularly lubricate the keyway with a graphite or silicone-based lubricant and inspect fixing screws periodically. If additional security features are needed (e.g., anti-snap, anti-bump), consider selecting a cylinder with those certified protections; the E50N is intended as a basic mechanical cylinder for standard use.
