We assume here that you are looking for a profile cylinder. The size of a cylinder lock depends on two factors: the thickness of the door and the thickness of the door fittings. The measuring methods are for measuring a loose whole cylinder, a loose half cylinder and a cylinder that is still in the door.
If you are going to buy a lock, there are two important dimensions that apply: the backset and the lock recess. The lock recess is the distance between the handle hole and the lock hole or keyhole. The backset is the distance from the handle and the lock hole and from the edge of the door. In this blog article we talk about the slot recess and backset.
Measuring the shields or the shield door fittings is not really difficult. Indoor door handles are available in two variants. Door handles on rosette and door handles on shield. With rosette door handles, the door handle is mounted on a small round or square plate. The plate for the lock or toilet closure is separate from the door handle.
Installing door fittings is not very difficult, but can sometimes pose minor challenges. Does your current door fitting need to be replaced, or have you just purchased a new door that still needs to be fitted with a suitable door handle or knob? After reading a short explanation, you can easily install your door fittings yourself.
Measuring door fittings is always the first step when purchasing new door fittings. It is of course important to know exactly how big this should be so that it fits properly in your door. Door knobs, handles and handles are available in all shapes and sizes, so it is important to make the right choice here.
