Fuhr genuine gearbox with split spindle function and available with a 35mm backset.
Please note that there has been two variations of latch sizes. Older version is 28mm high and latest version is 33mm high. The older version is no longer made but if you are replacing an older version then assuming the latch is not damaged on the original case it can be removed and applied to the new gearbox.
Operation: Lift lever or split spindle
Latch reversal: Undo the screw in the side of the lock case adjacent to the latch. Remove the latch, reverse, reinsert and replace the screw.
Nightlatch reversal: Insert the split spindle 2/3 of the way in on the internal side and 1/3 of the way in on the external side.
