Abstract
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.
