Query: SU(7) SUSY GUTs with a natural intermediate scale   We investigate the SU(N) supersymmetric Grand Unified Theories with
``custodial symmetry'' mechanism to explane the doublet-triplet hierarchy. We
show that in such type of SU(7) SUSY theory intermediate scale appears
naturally and the correct value for sin^2(\theta)_W is predicted via
vector-like matter superfields splitting. The unification appears to be closed
to M_Pl for all the reasonable values of \alpha_s and M_SUSY. Due to the large
unification scale the baryon number violating d=5 operator is suppressed in
comparison with that in minimal SU(5) theory.
