For cable guardrail systems, follow the manufacturer's instructions for installing and using U-bolt and double saddle type wire rope clips. If these specifications are unavailable, a competent person should determine the number of U-bolt clips and the installation torque required. Malleable cast-iron wire rope clips should not be used for hoisting or other critical applications unless approved by the manufacturer for that purpose. [1]

When using U-bolt clips, install them so that the U-bolt section bears on the short or dead end of the rope, while the saddle bears on the long or live end of the rope. Ensure the nuts are correctly torqued, and the number of clips and rope turn-back conform to the manufacturer’s specifications and instructions. [2]

For double saddle or fist clips, ensure they are installed in numbers and with the amount of rope turn-back specified by the manufacturer. If double base clips are used, ensure that the clips are at least 6 rope diameters in length. [2]

Cable clips used for fastening wire rope should be installed and torqued to the manufacturer's specifications, or to the values specified in Schedule 5 in the absence of manufacturer's specifications. Double-saddle clips (fist clips) used for fastening wire rope are to be installed using the number and the spacing and torque that complies with the specifications in Schedule 5\. Double-base clips used for fastening wire rope are to be installed with a spacing that is not less than 6 times the diameter of the rope. [3]

When installing U-bolt cable clips, the U-part goes over the dead end, while the live end rests in the clip saddle. Tighten the nuts evenly to the recommended torque. [5]

Ensure that wire ropes, sheaves, spools, and drums used in rigging have a diameter not less than the diameter specified by the manufacturer. The rope used in rigging should be the correct size for the sheave, spool, or drum over which it passes, and the grooving of wire rope sheaves should be the correct size for the wire rope used. End fittings and connectors used on a wire rope should conform to the manufacturer's specifications regarding number, size, and method of installation. Rigging blocks should be constructed and installed so that the ropes cannot jump off the sheaves. [4]

As a best practice, use at least three clips when making any prepared loop or thimble-eye termination for wire rope, especially for hoisting. All clips must be installed with the saddle part on the live end of the rope, allowing the live end to rest in the saddle so it's not crushed by the U-part of the clip. The U-part goes on the dead end of the rope where crushing will not affect the breaking strength of the hoist line. [5]

After installing the clips, apply tension and tighten all nuts to the recommended torque. Check the nut torque again after the rope has been in operation. [5]

When U-bolt wire rope clips are used for form eyes, the U-bolt should be applied so that the "U" section is in contact with the dead end of the rope. [6]

# Wire rope-Cable clips ## Explain dangers There's only one right way to install u-bolt cable clips when you want to get the maximum efficiency-up to 85%-out of a prepared loop or thimble-eye termination. Otherwise the capacity of the termination can be severely reduced, risking the lives of workers and others nearby. Because u-bolt clips are often installed incorrectly, double saddle clips (i.e., J-clip or fist grip clips) are preferable. Never use u-bolt clips when working with suspended access equipment. ## Identify controls Remember this when installing u-bolt cable clips: • Most cable clips have two sections. There's a saddle part and a U-shaped part. You need the right-sized clip for the wire rope diameter. • You need to know the number of clips required, the amount of rope to turn back from the thimble, and the torque needed to tighten the nuts. There are tables that spell out all of this information. (See below.) • As best practice, use at least three clips when making any prepared loop or thimble- eye termination for wire rope, especially for hoisting. - All three clips must be installed with the saddle part on the live end of the rope. This lets the live end rest in the saddle so it's not crushed by the U-part of the clip. - The U-part goes on the dead end of the rope where crushing will not affect the breaking strength of the hoist line. <table><tr><th>Rope Diameter (inches)</th><th>Minimum Number of Clips</th><th>Rope Turn- back from Thimble (inches)</th><th>Torque for Unlubricated Bolts (ft-lb)</th></tr><tr><td>5/16</td><td>2 1</td><td>51/2</td><td>30</td></tr><tr><td>3/8</td><td>2</td><td>6 1/2</td><td>45</td></tr><tr><td>7/16</td><td>2</td><td>7</td><td>65</td></tr><tr><td>1/2</td><td>3</td><td>11 1/2</td><td>65</td></tr><tr><td>9/16</td><td>3</td><td>12</td><td>95</td></tr><tr><td>5/8</td><td>3</td><td>12 2289</td><td>95</td></tr><tr><td>3/4</td><td>4</td><td>18</td><td>130</td></tr><tr><td>7/8</td><td>4</td><td>19</td><td>225</td></tr><
