Knob cylinders (Euro profile cylinders)

Knob cylinders are an essential component of your home or office security. These special cylinders, also known as euro profile knob cylinders, feature a convenient turn knob on the inside of the door. This allows you to quickly lock the door from the inside without a key, offering extra peace of mind and comfort. Whether you opt for a standard knob cylinder or a high-security version with added protection, it's important to choose a product that suits your specific needs.

Types of Knob Cylinders

There are various types of knob cylinders, each with their own features and security levels:

• Standard knob cylinders: Basic security, suitable for interior doors or low-risk areas.
• Security knob cylinders with SKG certification: Independently certified for quality and resistance.
• Knob cylinders with anti-pull protection: Offer extra resistance against burglary techniques such as core pulling.

What to Consider When Buying

When choosing the right knob cylinder, make sure to consider:

• The SKG certification and its star rating: more stars means better burglary resistance.
• The presence of core pull protection: prevents burglars from pulling the cylinder out of the door.
• The dimensions of the cylinder: measure your cylinder precisely. You’ll find detailed instructions on our page "How to measure a door cylinder".
