The FH003 Extended Precision V-Groove bare fiber holder is designed for use on the I3000, I3005, I5000, I5005, I6000, I6005 and RYP3000. The Extended V-Groove fiber holder is longer to reach out to the coincident rotation point. Special slide attachment features allow this fiber holder to be user adjusted for the desired projection. The hardened stainless steel precision V-Groove has been sculpted at the end for easy fiber visibility as alignment occurs. Dual action clamps and springs make for excellent fiber holding without breakage. Clamping force is set so the fiber is held firmly, yet can be pushed through the clamp by the operator. Spring tension can be custom factory set for any desired clamping force.
