  • Patent number: 5463189
    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.

  • Patent number: 5141185
    Abstract: A wiring clip for stud frame dry wall construction holds various forms of wiring a required distance from the nearest edge or face of the stud to which the dry wall is secured. A wire form of the clip is particularly suitable for wood studs while strap forms may be used with studs made of metal or wood or other material. Each form of the invention includes an L-shape portion adapted to be secured to the face and/or side of the stud. Extending from such L-shape portion parallel to and recessed from the edge of the stud (interior of the wall board) is a strut and arm with the arm being hinged at the end of the strut remote from the L-shape portion and adapted to be folded back to extend parallel to the strut and locked in place to embrace wiring between such arm and strut. Each form of the clip is easy to install and accommodates a variety of types of wiring. The clips may be crimped by pliers tightly to embrace and conform to the wiring after installation.
