  For a special family of 4d $\mathcal{N}=2$ superconformal quiver theories,
the worldsheet dual corresponding to the free theory is identified. This result
is obtained from the recently proposed worldsheet dual of free $\mathcal{N}=4$
SYM by applying a $\mathbb{Z}_k$ orbifold. In support of our proposal we show
that the spectrum of both the untwisted as well as the twisted sectors
coincides between the two descriptions.
