Abstract
A cable closure end cap arrangement is provided, to achieve a sealing between a cable splice closure, and a cable end in communication therewith. The arrangements according to the invention may be adapted to accommodate more than one cable extending into an end of a cable closure. Preferred arrangements comprise a composite of inner and outer members, each having a bore therein. Each bore is preferably defined by an arrangement of concentric rings, or a circular ridge/trough arrangement. The circular rings include transverse walls extending therebetween, in a preferred manner permitting an accordion-like flexibility. The accordion-like rings accommodate; cables of different sizes; cables at various angles relative to the end cap arrangement and the cable closure; and, movement of the cable closure, for example upon an aerial messenger wire. End cap arrangements according to the present invention are mounted by means of a slit in communication with each bore. The slits are preferably prepared by cutting slots formed in the end cap arrangement during manufacture. Preferred end cap arrangements are made from a rubber, or thermoplastic rubber material, for flexibility and long life.
