A tape applying assembly may be defined within the body that is configured to adhere the tape to both the at least one cable and the surface. A cable alignment assembly may also be defined within the body that is configured to receive at least one cable positioned against the surface and substantially align the at least one cable with the tape center longitudinal axis.
