ERA Invincible Cylinder Locks
When ordering a new euro cylinder the two most important measurements you must obtain are the internal size and external size of the existing euro cylinder. These are simply measured from each end of the cylinder to the centre of the screw hole in the middle of the cylinder. All measurements are in millimeters.
This is the unique invincible door cylinder lock by ERA made to suit their invincible door locks. The cylinder has been built to achieve 5 times more break resistance strength than a normal sized euro door cylinder.
