Operation: Lift lever or split spindle
Latch reversal: Undo the screw in the latch to remove it. Reverse and reinsert then replace the screw.
Nightlatch Reversal: The lock is supplied as a lift lever function, it is fitted with a travel pin on the surround of the spindle hole. This must be broken in order to convert to a split spindle function.
To break the travel pin, simultaneously lift the outside handle up and the inside handle down, you should hear the crunching noise of the pin breaking.
The split spindle function is now activated and with the spindles set into the correct position the latch will now only open via the key from the outside and by the handle from the inside.
The follower of a Fullex lock is split into 3 parts, Using a Genuine Fullex Split Spindle(our part number SPLITSPIN), the longer spindle must go on the inside and should overlap 2 parts, the shorter spindle is to be
placed on the outside and should only engage with the first part.
