This patent application is submitted for a CNC/ILDS sleeve and RC removable collar designed to provide a means of protecting fence cables and posts. Without such protection a conventional rock fall protection fence frequently fails upon impact from large falling rocks spinning at a high angular velocity and with an immense momentum, as demonstrated in many rock fall-induced fence failures. CNC/ILDS sleeves embrace a cable or post to deflect falling rocks spinning at a high angular velocity and associated impact forces and, thereby, protect them by avoiding detrimental blows from the falling rocks. The RC (removable collar) is used when two different-size CNC/ILDS sleeves are used. This is to avoid a smaller sleeve from slipping into a larger one and to assure the protection that CNC/ILDS sleeve is designed for. Additionally, the RC collar also enhances the constructability and eases the maintenance of a rock fall mitigation fence system. In summary, the CNC/ILDS sleeve together with the RC removable collar embraces the fence cable and post, provides a means of their protection, and enhances the safety of traveling motorists.

A method for protecting cables and posts from damage by providing at least one first sleeve cut to a desired length, positioning each first sleeve over the cable, inserting a screw through an aperture on a last first sleeve positioned on the cable until the screw contacts the cable, providing a second sleeve having an inside diameter greater than an outside diameter of the first sleeve, positioning the second sleeve over the first sleeves, tensioning the cable, securing an end of the cable, sliding the second sleeve over the end, positioning a removable collar assembly between the first and second sleeves, maintaining the first and second sleeves from overlapping the removable collar and each other, maintaining the first and second sleeves from connection with each other, removing the holding screws from the last first sleeve, and rotating the sleeves and the removable collar assembly independently from each other.

A guard system for protecting cables and posts from damage by falling rocks and other dynamic forces is provided. The guard assembly comprises a first sleeve rotatably positioned about the cable or post and a second sleeve rotatably positioned about the cable or post. A removable collar assembly is positioned between the first sleeve and the second sleeve for maintaining the spacing between the first sleeve and the second sleeve.
