Double cylinders (Euro profile cylinders)

Double cylinders are an essential component of the security of your home or office. These cylinders, also known as euro profile cylinders, allow you to operate both the inside and outside of a lock with a single key. This makes them especially practical in situations where quick access is needed. Whether you're looking for a basic double cylinder or a version with extra security features, there is always a model that suits your specific needs and budget.

Types of Double Cylinders

When choosing the right double cylinder, it's important to consider the following aspects:

• SKG certification: Indicates how burglar-resistant the cylinder is.
• Anti-snap protection: Prevents the cylinder from being pulled out of the lock.
• Drill protection: Guards against drilling attacks.
• Keyed alike cylinders: Operate multiple cylinders with a single key.

FAQ: Frequently Asked Questions About Double Cylinders

What is a double cylinder and when is it used?

A double cylinder, also known as a euro profile cylinder, is a lock cylinder that can be operated from both sides with a key. It is commonly used for front doors, back doors, and other exterior doors where operation from both sides is desired.

What’s the difference between SKG, SKG**, and SKG*** cylinders?

The SKG rating indicates how resistant a cylinder is to burglary:
SKG** provides standard resistance (3 minutes delay).
SKG*** offers high resistance (5 minutes delay) and extra protection against cylinder snapping.
For optimal security of your home or business, SKG*** is recommended.

Why is anti-snap protection important?

Cylinder snapping is a common burglary method where the cylinder is forcibly pulled out of the lock. Cylinders with anti-snap protection feature a special steel plate to prevent this attack. This is now essential for a secure front door.

Can I operate multiple cylinders with one key (keyed alike)?

Yes, many cylinders can be ordered keyed alike. This means you can open multiple doors with the same key. Ideal for homes with multiple entrances, sheds, or office spaces.

How do I know which cylinder size I need?

The size is determined by measuring from the center of the screw hole (retaining screw) to both ends of the door. On our page “Measuring a (door) cylinder” you’ll find clear instructions. Not sure? Our customer service is happy to help.
