Euro Profile Locks

These are mortice lock cases which are all designed to accept euro-cylinders, so if you are looking to replace your existing euro lock case or are looking to upgrade from a 5-lever lock to a euro profile lock, then you're in the right place. 

If you're looking to replace an existing euro-profile mortice lock, then the easiest route with be a like-for-like replacement, or if this is not possible or you wish to avoid using the same lock again for any reason, then assuring that the critical measurements are the same will prevent you from having to make modification.  To help you with this we have put together a complete lock measurement guide for each type of door lock. 

However, if you're looking to upgrade from a 5-lever lock to a euro-cylinder lock case, then modification is very likely to be required, unless there has previously been a euro lock fitted on the door.  This is because a euro cylinder requires a bigger space than a standard keyhole drilled through the door, and in addition to this, the centres measurement which is the distance between the keyway and the handle is also different, usually around 57mm on a 5-lever lock, but typically only 48mm on a standard euro profile lock case (with some exceptions on DIN standard locks etc, which would be between 70mm and 92mm).

Also don't forget, if you're starting from scratch then make sure you also get yourself a euro profile cylinder to work with these locks!
