Service Dead Ends are used to make service drops on bare neutral messengers of self supporting cable. They are designed for minimum length, maximum economy and neatness of appearance. Service Dead Ends should not be reused after original installation. They are designed to be applied to spool insulators or wire holders having a smooth contour with diameters no less than 1 inch and no greater than 3 inches.

Distribution Dead Ends are recommended. For direct application onto plastic jacketed conductors Coated Dead Ends are recommended. The published Rated Holding Strengths listed on page 5 are actual test results on unweathered conductor and are conservative when compared to typical values.
Tapping over the applied legs of the Service Dead End is not recommended. Taps should be located either six inches from the gritted legs or on the neutral tail continued past the crossover point.
