  We examine unification of gauge couplings in four dimensional renormalizable
gauge theories inspired by the latticized (deconstructed) SM or MSSM in five
dimensions. The models are based on replicated gauge groups, spontaneously
broken to the diagonal subgroup. The analysis is performed at one-loop level,
with the contribution from the heavy vector bosons included, and compared with
the analogous results in the SM or MSSM. Unification at or above the diagonal
breaking scale is discussed. We find that in the considered class of extensions
of the SM(MSSM) unification is possible for a wide range of unification scales
and with the similar accuracy as in the SM(MSSM). Unification above the
diagonal breaking scale is particularly attractive: it is a consequence of the
SM(MSSM) unification, but with the unification scale depending on the number of
replications of the gauge group.
