1. An exothermic reaction mold kit comprising:
a plurality of bushings, each of the plurality of bushings includes:
a first bushing portion having an outer diameter that is uniform along a width of the first bushing portion;
a second bushing portion adjacent the first bushing portion and having an outer diameter that is uniform along a width of the second bushing portion, wherein the uniform outer diameter of the first bushing portion is larger than the uniform outer diameter of the second bushing portion;
a third bushing portion adjacent the second bushing portion and having an outer diameter that is uniform along a width of the third bushing portion, wherein the uniform outer diameter of the third bushing portion is larger than the uniform outer diameter of the second bushing portion; and
an orifice extending through the first bushing portion, the second bushing portion and the third bushing portion, the orifice having an inner diameter dimensioned to receive a cable; and
an exothermic reaction mold including:
a reaction chamber;
a weld chamber in communication with the reaction chamber; and
a plurality of user configurable ports, each user configurable port being in communication with the weld chamber, each user configurable port having a bushing holding portion, each bushing holding portion having a first portion and a second portion, wherein the first portion has a shape that corresponds to a shape of the first bushing portion so that the first portion can removably receive the first bushing portion, and wherein the second portion has a shape that corresponds to a shape of the second bushing portion so that the second portion can removably receive the second bushing portion.
