What are security cylinders?

Security cylinders are easy to install as hardly any tools are required and come in a range of shapes and sizes to suit many different applications.

How to measure security cylinders?

Industry professionals can sometimes have different ways of measuring cylinders. Here at DOM we follow the conventional industry method. Measuring the Interior of the door thickness first (Dimension A) followed by the Exterior (Dimension B) This is the same with both double cylinders and key and knob cylinders (The knob is always on the inside). To measure a cylinder, measure from the very edge to the centre point of the screw hole. With a single cylinder again measure from the leading edge to the centre point of the screw hole (Dimension A) But the internal side (Dimension B) will always be 10mm.

What is a Masterkey System?

A Masterkey System is a key plan that allows a key or set of keys to provide specific access to a number of pre-defined doors. The system functions like a hierarchy providing access to different key holders such as building owners, facilities managers or members of staff. A system like this ensures greater control and convenience as it provides quick access to all rooms, saves key replacement costs and increases safety as management and security staff can access any room if required.
