Knob cylinder locks

Buy a cylinder lock with a rotary knob: Security and convenience for your home or business

Are you looking for a safe and practical way to secure your entrance doors? A cylinder lock with a rotary knob is the ideal choice: with a simple turn, you can open the door from the inside, without using a key. Perfect for homes and businesses.

What is a cylinder lock with a rotary knob?

A cylinder lock with a rotary knob is a type of cylinder lock that can be operated on one side with a rotary knob instead of a key. This allows you to easily open or lock your door. When used on exterior doors, the knob side is logically placed on the inside of the door.

The lock on the other side (street side) can only be operated with a key. This makes a knob cylinder just as secure as a two-way key-operated profile cylinder.

When to buy a cylinder lock with a rotary knob?

  • Front door: A knob cylinder for the front door is a popular choice because of its ease of use. There's also another advantage: a knob cylinder can always be operated from the key side. This means you don't have to worry about a locked door if the key is in the lock on the inside.

  • Interior doors: For interior doors in treatment rooms, practice rooms, or consulting rooms, cylinders with a rotary knob are ideal. The door can be locked quickly and easily without a key. For specific applications, such as doors that only need to be locked on one side, you can purchase a single-sided knob cylinder.

  • Escape routes:For doors that are part of an escape route, a knob cylinder offers a solution. In an emergency, the door can always be opened, even if it is locked with the key on the other side.

  • Caution for exterior doors:In some situations, it is less advisable to purchase a knob cylinder, such as for exterior doors with a glass panel without burglar-resistant glass. Uninvited guests can smash this glass and open the door via the knob cylinder. Are you unsure whether a knob cylinder is suitable for your situation? For advice, you can always contact us.

What should you consider when buying a cylinder lock with a knob?

Before buying a knob cylinder, it's important to consider:

  1. Dimensions: Measure the exact dimensions of the knob cylinder you need. Read here's a detailed explanation about measuring the cylinder. The length of the knob cylinder should match the thickness of your door. If the length of your cylinder on the knob and key sides isn't the same, check which side is the knob. When purchasing a knob cylinder in the webshop, the inside measurement is the knob side.

  2. SKG* certification: Does the application of your knob cylinder require an SKG2* or SKG3* certification? Our staff can always advise you on purchasing the right knob cylinder.

  3. Keyed alike: To order a knob cylinder that can be operated with your current key, select the "Keyed alike" option in the webshop.
