  We study a left right (LR) extension of the Standard Model (SM) where the
Dark Matter (DM) candidate is composed of a set of fermionic Majorana triplets.
The DM is stabilized by a remnant $Z_{2}$ symmetry from the breaking of the LR
group to the SM. Two simple scenarios where the DM particles plus a certain set
of extra fields lead to gauge coupling unification with a low LR scale are
explored. The constraints from relic density and predictions for direct
detection are discussed for both scenarios. The first scenario with a $SU(2)_R$
vectorlike fermion triplet contains a DM candidate which is almost
unconstrained by current direct detection experiments. The second scenario,
with an additional $SU(2)_R$ triplet, opens up a scalar portal leading to
direct detection constraints which are similar to collider limits for right
gauge bosons. The DM parameter space consistent with phenomenological
requirements can also lead to successful gauge coupling unification in a
$SO(10)$ setup.
