Screw Stub Adjustment Ranges

All measurements are from the centre of the spindle

Lock Series	Top Screw Stub Type	Top Stub Range (Up from Spindle)	Bottom Screw Stub Type	Bottom Stub Range (Down from Spindle)
SF / SFS (Slim Series)	Adjustable	60–95 mm	Fixed	72–92 mm (fixed at 85 mm)
EF (V3 – Newest version)	Adjustable	65–110 mm	Fixed	72–92 mm (fixed at 85 mm)
SS	Adjustable	55–125 mm	Adjustable	55–125 mm

“Up” and “Down” are always measured from the centre of the spindle
“Effective range” means the usable fixing range, regardless of the fixed stub position
If door fixing points fall outside these ranges, the lock will not fit correctly

Applies to Slim series, SS, and EF models
