  We investigate orthosymplectic quivers that take the shape of D-type and
B-type Dynkin diagrams. The D-type orthosymplectic quivers explored here
contain a balanced "fork", i.e., a balanced subquiver with a D-type
bifurcation, whereas the B-type orthosymplectic quivers are obtained by folding
the D-type quivers. The Coulomb branches of these quivers are products of two
moduli spaces. In the second part, the relevant orthosymplectic quivers are
shown to emerge as magnetic quivers for brane configurations involving ON$^0$
planes. Notably, the appearance of ON$^0$ plane clarifies the product nature of
the theories in question. The derivation leads to the analysis of magnetic
quivers from branes systems with intersecting Op, O(p+2), and ON$^0$ planes.
