Katimex® Flexi-Probe 2.0. The Flexi-Probe 2.0 offers, thanks to its conical shape, an optimal introduction of the bending forces into the glass fibre profile when passing through tight bends. The probe is not subject to material fatigue like a spring guide head, for example. Together with the new starting sleeve 2.0, it forms the optimal tool for passing through very tight bends. Bending radii of 30 mm are possible. Head Ø 7 mm
