It’s only fitting that CERTIFIED WIRE ROPE & TESTING’S drill line is engineered and tested for the toughest drilling conditions on Earth — right here in Alberta, Canada. DURAFLEX® drilling lines are manufactured at XIANYANG BOMCO STEEL, an ISO 9001-certified, API-registered facility, and a proud partner of CERTIFIED WIRE ROPE. These ropes meet or exceed all federal specifications (RR-W-410). Every drill line is 100% guaranteed for unmatchable quality and performance and accompanied by serial-numbered factory test certificates with records kept at CERTIFIED WIRE ROPE & TESTING.

We recommend regular on-site inspections, which we are happy to provide as needed or required. Inspections can be provided on an as-needed or as-required basis. To ensure your rig operates at its full capacity and efficiency, complimentary and correct “slip and cut” programs are available. The most valuable word in Wire Rope 101 is “inspection,” we are all responsible!
