Which profile cylinder fits my door?

The choice of the right profile cylinder for your door depends on several factors.

The first step is to measure the door. The length of the cylinder must match the door thickness. Measure from the center of the screw hole (usually on the B-side of the door) outward to the ends of the existing cylinder escutcheon. These measurements are usually given in millimeters, for example as 30/30 or 35/45.

In addition, you should consider the security requirements:

• Standard profile cylinders offer basic security protection and are usually the most affordable option.
• Security profile cylinders offer increased protection, for example through drill protection and anti-drilling protection.
• High-security profile cylinders offer the highest level of protection. They feature additional security functions such as anti-drill and pull protection, as well as an emergency and danger function, which allows you to continue locking the door with a key even if a key is stuck in the cylinder.

Finally, you can consider the brand and value for money. There is a wide range of brands offering profile cylinders, including BKS, ABUS and KESO. Each brand offers different price points and security levels.
