DURAFLEX®, DURAFLEX SC®, DURAFLEXCORE 9®, DURAFLEX 9 ® (Patented Core), DURAFLEXCORE 35® (Patented Core), PINK LINK®, AND ‘WILD ROSE®’ (pink strand) are proudly owned trademarks/PP of CERTIFIED WIRE ROPE.



New Product


In early 2016 we will be introducing the newest addition to our DURAFLEX® line of quality wire rope products. DURAFLEXCORE 9® is a high strength swaged rope compacted rope designed and engineered to resist abrasion and well suited for main boom hoist and tubing applications. A specific swaging process combined with the addition of polymer ‘wires’ within the outer strands ensure a flexible yet extremely tough product to help combat drum crushing particularly on multi-layered drums. Extra lubrication is extruded deeply into the outer strands and to the core helping prevent potential dryness and significantly increasing rope operating life.

Current trials are recording a longer service life increase by as much as 3 times that of typical ropes used on crane boom lines and well servicing equipment.

NOTE: Because of the swaging process, DURAFLEXCORE 9® will have no exterior pink ‘WILD ROSE’ strand as an identifying marker. The cores of each outside strand will however be created with pink polymer ‘wires’ for easy identification as a CERTIFIED manufactured product.
