(1) The use of cable clips or clamps for joining lines is prohibited, except where used for transferring slack lines from one place to another. Figure 7-2 — Wire Rope U-Bolt Clip Figure 7-3 — Wire Rope Fist Grip Clip [Figures not included. See ED. NOTE.] (2) When U-bolt wire rope clips are used, the following requirements apply: (a) When used for eye splices, the U-bolt wire rope clip must be attached so that the "U" section is in contact with the dead or short end of the rope; Figure 7-4 — U-Bolt Clip Installation [Figure not included. See ED. NOTE.] (b) U-bolt wire rope clips must be spaced at least six rope diameters apart to obtain the maximum holding power. Nuts must be tightened evenly and tightened again after application of the first sustained load. After the rope has been used and is under tension, the clips must be tightened again to take up any looseness caused by the tension reducing the rope diameter; (c) When high strength wire rope is used, one more U-bolt wire rope clip must be added for each grade above improved plow steel; and (d) U-bolt wire rope clips must not be used to form eyes on running lines, skylines, or straps. (3) When U-bolt wire rope clips are used to form eyes, Table 7-3 must be used to determine the number and spacing of clips. Table 7-3 — Number and Spacing of U-Bolt Wire Rope Clips [Table not included. See ED. NOTE.] [ED. NOTE: Figures and Tables referenced are available from the agency.]
