ABSTRACT:
A cord grip in which two screw fittings provide a variable volume chamber for compressing a flexible soft durometer grommet held within a flexible annular cord gripping member. The cord gripping member is of a harder durometer than the grommet and has a plurality of fingers for gripping the cord. The combination of the hard durometer cord gripping member and the soft durometer grommet provides positive gripping action and a liquid tight seal on the cord when the variable volume chamber within the fittings is in the compressed state.
