This Blade Holder Plastic 100% ORIGINAL is suitable for all Roland printers with cutting option. This is the original Roland part (number XD-CH3 replacing 22205139). This blade holder can be used on all Roland printers / cutting plotters instead of the XD-CH2 holder. The CH3 holder throw-off-help and gauge-scale make it easier to handle for users who need to change the knife deepness and the knife often.
