Suspension or Tangent clamps are used to support the cable weight at intermediate poles where no significant tension exists. They are typically of 3-bolt configuration with the central bolt mounting the fixture to the pole and the outer two bolts are used to compress the clamp onto messenger component. There are three kinds of tangent clamps depending on “Pull at a Pole”.

“Pull at a Pole” can be determined as follows:-

1. A distance of 100 ft. (30.48m) is measured along both intended cable span directions. These points are marked by stakes or other means.
2. Measure the distance between these two points.
3. Mark the mid pint of this distance.

The distance of this mid point from the pole is called “Pull at a Pole”.

Now depending on this “Pull” there can be three types of tangent clamps.

	C-Cable Clamps or Serpentine Clamps
	Straight Suspension Clamps
	Corner Suspension Clamps
