ABSTRACT:
An overhead line marking device that is installable from one end thereof. The marker device is formed from two bodies and when installed includes two identical hinge/retaining assemblies at each end. Each hinge/retaining assembly includes a lower support plate, at least one U-shaped retaining leg member and an extension tongue as part of the upper body. Prior to installation, the far hinge/retaining assembly will be performed by attaching at least one U-shaped leg member onto the support. This forms a retaining groove that can receive and in which the tongue extension can rotate. During installation the tongue extension will be inserted into the far hinge/retaining assembly, after the lower body is secured to the overhead line, and the near hinge/retaining assembly is then completed forming an enclosed marker device about the overhead line.
