What are Security Cylinders?

Security cylinders, also known as pin tumbler locks, are essential for securing doors both internally and externally in residential and commercial properties. As the most widely used locking mechanism, these cylinder locks offer easy installation, requiring minimal tools. Available in a variety of shapes and sizes, security cylinders are ideal for numerous applications.

How Do I Measure a Security Cylinder Lock?

At DOM UK, we adhere to the standard industry method for measuring security cylinder locks. Start by measuring the exterior door thickness, followed by the interior. To accurately measure a cylinder lock, measure from the outer edge to the center of the screw hole. This method ensures a precise fit for your building's security system and ironmongery needs.
