Abstract: An installation clip has a base member that fastens to first electrical cable already secured to a structural member in order to mount one or more second electrical cables indirectly to the structural member. A clip structure is disposed on the base member and has a pair of resilient retaining arms that extend outwardly from the base member in opposed, spaced-apart relation to define a clip channel into which the second electrical cable(s) can be placed. Shoulders may be formed on the distal ends of the retaining arms to define an inlet into the clip channel, and lips may be disposed on the shoulders to form a V-shaped opening into the clip channel. The retaining arms may also have opposed central flanges that project into the clip channel parallel to the base member to form upper and lower regions, and a spacer may also be disposed on the base member to separate the lower region into a pair of subregions. These regions are each sized to receive a second electrical cable.
