Abstract: A device includes a tensioning member including a head portion and a cylindrical portion. The head portion includes a first bore and a second bore in communication with the first bore. The cylindrical portion extends from the head portion towards a second end and includes one or more threads. A device may include a set screw member including threads formed along its length. The set screw member may couple to the first bore and retains an electrical conductor positioned in the second bore in connected engagement with the tensioning member. The tensioning member is configured to contact an elongate article to electrically connect the elongate article to the tensioning member and the electrical conductor. A device may also include a strap member. The strap member extends around the elongate article and the tensioning member applies a tension force between the strap member and the elongate article.

Abstract: A device may include a strap member, a tensioning member, a first nut, and a second nut. The strap member includes a first portion, a second portion, and a third portion contiguously connected to the first portion and the second portion. The first nut is coupled to the tensioning member adjacent a first end of the tensioning member. The tensioning member extends through the first nut and contacts a surface of the elongate article to apply a tension force and to electrically connect the elongate article to a grounded electrical conductor. The second nut is coupled to the threaded cylindrical member adjacent a second end and acts on the first nut to retain the position of the tensioning member relative to the first nut. The second nut can also act on a compression lug to place the compression lug in connected engagement with the tensioning member.
