Energex Entrance Double Cylinder- I will need your door handing and the backset 60 mm or 70 mm for correct assembly
( Backset- distance from edge of door to cente line of the lock- it is either 60 mm or 70 mm)
( Handing- Standing on the outside of your door- is the knob on the left hand side or the right hand side? )
Let me know both your handing and your backset measurement in the notes or I will have to ring you
Knobs are lockable and un-lockable on this lock
(if your neighbour purchases a lock then that is a different key, but the meter reader master key fits everybody’s lock)
