A practical application of Quadri*Sil™ line posts is for support of jumper loops on transmission lines.

Horizontal motion of the jumper is restricted, and the factor of wind sway is eliminated. Additionally, the crossarm length may be reduced. The difference in cost of insulation is not significant, but the saving in tower cost can be attractive. Regardless of cost, the use of a jumper support improves construction.

If using a single clamp, clamp postition relative to the insulator may be changed by bolting the clamp through the upper hole in the insulator end fitting.

Jumper clamps are not intended for tangent span applications.
