How to Install U-Bolt Cable Clamps

U-bolt clamps can be used to join two metal cables together or to make a loop in a length of cable. The U-bolt clamp is made up of a U-shaped bolt with threaded ends and a "saddle" piece that slides over the end of the bolt. Two hex nuts tighten the bolt section against the saddle and clamp the two cables together. When used correctly, the U-bolt clamp creates a very strong connection.

Things You'll Need

  • Tape measure

  • Marking device

  • Socket set

  • 3/8-inch drive torque wrench

Step 1

Measure the diameter of the cable. The packaging information that comes with the clamps will tell you the number of clamps you will need based on the cable diameter.

Step 2

Remove the two hex nuts from the threaded ends of the U-bolt and slide the saddle piece off the U-bolt.

Step 3

Hold the pieces of cable together and place the U-bolt over the cut end of the cable. Slide the saddle piece over the U-bolt and hold the two sections together. Thread the hex nuts onto the U-bolt by hand and up to the base of the saddle piece. Hand-tighten the two hex nuts.

Step 4

Refer to the packaging information to determine the spacing for the rest of the cable clamps.

Step 5

Use a tape measure to measure the distance from the first cable clamp and make a mark on the cable at the distance specified in the packaging information.

Step 6

Repeat Steps 2 through 5 for the number of clamps specified in the packaging information.

Step 7

Set the torque wrench to the specified setting given in the packaging information and tighten each hex nut. The cables are now joined.

Warning

If you use the U-bolt clamps incorrectly, the cut wire can slide out from the clamps. Be sure to follow the packaging instructions.
