Fiber fixing chucks of model FH-70-12/4/6/8/10, in 5 sizes, are applicable for replacing those of Fujikura FSM-70R and 88R 

 This fixture does not have a V-groove. It presses more tightly and evenly than the fixture with a V-groove, solving the problem that the fixture with a V-groove cannot be used once the V-groove is worn out. If you need a fixture with a V-groove, please contact our customer service.
