SKG 2 or SKG 3 stars?

All cylinders in our online store have an SKG star quality mark. In this blog you can read what this quality mark means and what the number of stars actually says about the cylinder.

What is the SKG quality mark?

SKG stands for Foundation Quality Gevelbouw. This independent inspection institute was established to inspect and certify the burglary safety of hinges and locks. Products are tested by this organization according to a clear guideline for the degree of quality and burglar resistance. If the product is tested positively on several levels, it will be qualified with a number of stars.

What does the number of stars mean?

The number of stars is awarded based on the delay it causes the burglar to gain entry. So the higher the number of stars, the longer it takes to open the cylinder without a key.

• SKG 2**
  Cylinders with an SKG 2** quality mark offer resistance to a burglary attempt for at least 3 minutes. A cylinder with 2** has a drill protection. This makes it very difficult to drill open the cylinder from the outside. This cylinder does not have core pulling protection, so it is wise to only install it if the security fitting is equipped with protection against core pulling.
• SKG 3***
  Cylinder locks with SKG 3*** offer the highest protection against burglary. This cylinder causes a delay of at least 5 minutes. In addition to drilling protection, these cylinders are also equipped with core pulling protection. You can use this door cylinder if your door fittings are not equipped with core pulling protection.

Security fittings and core pulling protection.

A well-secured door must therefore in all cases be equipped with SKG-approved security fittings in combination with an SKG-approved security cylinder. When purchasing new door fittings, it is very important to choose security fittings with core pulling protection. You can recognize Core Pull Protection by a metal disc in front of the keyhole that turns when you turn the key. As you have read previously, you can upgrade older security fittings without this security by installing an SKG 3*** security cylinder lock.

Structural security with a visible SKG quality mark has a very preventive effect. It is a time-consuming hurdle that certainly cannot be overcome silently. A smart burglar would rather pass your door in such a case, looking for an easier job...
