Insulating Blankets, Line Hose & Covers
To work on live lines safely, conductors encased in a line hose should never be placed directly on a cross arm. Cross Arm Covers reduce electrical stresses on line hose or jumpers. Cross Arm Covers fit standard cross arm pin spacing and each unit has interior ribs to minimize shifting on the arm.
