Claims26
An electrical cable clamp comprising:
- a base having a center opening;
- a first clamp member having a first end extending from the base and a second free end;
- a second clamp member having a first end extending from the base and a second free end, wherein the second free end of the first clamp member opposes the second free end of the second clamp member, wherein an area where the second free end of the first clamp member opposes the second free end of the second clamp member being a cable gripping area, and wherein the free end of the first clamp member and the free end of the second clamp member are shaped to flex imparting little resistance to advancement of a cable within the gripping area in a first direction, while imparting sufficient resistance to hold the cable in the gripping area;
- at least one inside snap-in tab having a camming surface that facilitates installation of the electrical cable clamp into an opening in an electrical box from outside the electrical box;
- and
- at least one outside snap-in tab having a camming surface that facilitates installation of the electrical cable clamp into the opening in the electrical box from inside the electrical box.
