The possibility that two toroidal accretion configurations may be
orbiting around a super-massive Kerr black hole has been addressed. Such
tori may be formed during different stages of the Kerr attractor
accretion history. We consider the relative rotation of the tori and the
corotation or counterrotation of a single torus with respect to the Kerr
attractor. We give classification of the couples of accreting and non-
accreting tori in dependence on the Kerr black hole dimensionless spin.
We demonstrate that only in few cases a double accretion tori system may
be formed under specific conditions.
