With PKP-ZRE 60/AB/50 reduction element we reduce the width for A/B (mm) = 50 mm (e.g. from cable tray of 100 mm of width to 50 mm; 200 mm/150 mm). With PKP-ZRE 60/AB/100 reduction element we reduce the width for A/B (mm) = 100 mm (e.g. from cable tray of 500 mm of width to 400 mm). The mounting is carried out with PPKP M6x12 (8x) connection bolts and PPKP M6 (8x) flange nuts.
