Cable clamps are also referred to as U-bolt clamp, U-bolt clip, Wire Rope clamp or Wire Rope clip.
* Torque values shown are based on clean unlubricated threads. Cable clamps are not designed for load carrying purposes. Therefore working load limits have not been established.

Proper Method for Assembling Cable Clamps
For OSHA (Construction) applications, see OSHA 1926.51
1. Refer to appropriate table when following these instructions. Begin by turning back specified amount of rope from thimble loop. Apply the first clamp as shown in Figure 1. Make sure that the U-Bolt is placed over the dead end of the wire rope, the live end rests in the saddle. (Never saddle a dead horse!) Tighten nuts evenly, alternating from one to the other until recommended torque is reached.
2. Apply the second clamp as shown in Figure 2, as close to loop or thimble as possible. If additional clamps are required, tighten nuts but do not torque and move on to the next step. If only two clamps are required, go ahead and alternate tightening of nuts until recommended torque is reached.
3. Apply the additional clamps as shown in Figure 3, spacing them evenly between the first two. Make sure to take up slack in rope then alternate tightening of nuts on all U-Bolts until recommended torque is reached.
IMPORTANT NOTES – ALWAYS match clamp size to the same size wire rope – ALWAYS prepare wire rope and end termination as instructed – NEVER use wire rope clips with plastic coated wire rope – ALWAYS apply “first load” to test the wire rope assembly. The test load should weigh more than or equal to expected working loads – ALWAYS check and retighten nuts to recommended torque.
