  • Patent number: 6182930
    Abstract: A packing piece half for a cable lead-through which may be adapted for different dimensions of cable is presented. A packing piece half includes a main portion which is essentially a parallelepiped and together with a second packing piece half, forms a rectangular cross section. The main portion has a cavity therein such that when placed together with the second packing piece half, a rectangular packing piece having a channel therethrough is formed. The packing piece half further includes upwardly directed tabs and/or horizontal tabs. Each tab is preferably integral to the main portion and has a frangible connection thereto. The tabs are constructed and arranged to be torn from the main portion and inserted into the cavity, thereby reducing its diameter to provide a tight fit to elongated members extending therethrough.
