As shown in the figures, each assembly has its own constant, which is set by the different arm heights. K Fig.1 K Fig.2 K Fig.3 (1)Full overlay arm:it has the highest constant to overlay the whole side (0mm cranking) (2)Half overlay arm:intermediate constant to overlay part of the side (10mm cranking) (3)Full inset arm: minimum constant for embedded doors (17mm cranking) & SEGNIHSGNITTIF TFIL
