  A binary system of identical corotating Kerr sources is studied after
deriving the corresponding 3-parametric asymptotically flat exact solution.
Both sources are apart from each other by means of a massless strut (conical
singularity). In the context of black holes, the analytical functional form of
each horizon {\sigma} is expressed in terms of arbitrary Komar physical
parameters: mass M, angular momentum J (with parallel spin), and the coordinate
distance R between the center of each horizon. Later on, all the
thermodynamical properties related to the horizon are depicted by concise
formulae. Finally, the extreme limit case is obtained as a 2-parametric
subclass of Kinnersley-Chitre metric.
