Construction and Design Flexicore® cables are crafted by tightly coiling heavy-gauge wire around a 49-strand aircraft-quality wire rope, then heat-treated. This design provides unparalleled strength and flexibility, enabling the cable to withstand increased torque during tough blockages with minimal kinking or breakage.
