HELICALLY PREFORMED WIRE-GRIPPING DEVICE HAVING DIFFERENT PITCH ANGLES WITHIN EACH CONVOLUTION THEREOF ABSTRACT OF THE DISCLOSURE Improved wire-engaging structure is disclosed for devices adapted to grippingly engage a wire or line. In one form of the invention a preformed wire line tie for securing elongate line conductors to a conventional support has a pair of conductor-engaging, coiled leg members particularly configured to permit substantially effortless installation while at the same time providing the zapability to grippingly engage a wide range of conductor sizes. The coiled members comprise a series of equi-lead, axially aligned convolutions each having helical segments of unequal helix angles. Alternate steep and shallow angles presented by the helical segments cooperate to provide required positive engagement with any one of a number of various size conductors while at the same time permitting the members to be easily positioned around the conductor. Other forms of the invention show the use of the equi-lead, multiple helix angle design concept for the coiled wire-engaging members in a deadend and an armor rod. (Dkt. 15967)
