4Point 14 is 4Point tonearm with 14 inch (353 mm) effective length which is fitted on 12 inch (291mm) distance position on the turntable.
The 4Point 14 inch tonearm just fits the Stabi M turntable with the use of a 12 inch cutout but some parts of the tonearm come very close to the edge of the lid.
To fit the tonearm on a Stabi M you need to change the distance from the spindle to the horizontal bearing. The standard distance is 340 mm and this must be changed to 338 mm so that the closed lid does not touch the tonearm. When the cartidge's geometry is adjusted the protractors will automatically compensate for this change. This change in effective length is minor and not important (just over 1%).
