Abstract In this paper, we study the relation between a space $X$ satisfying certain generalized metric properties and
the Pixley-Roy hyperspace $\mathcal F[X]$ over $X$ satisfying the same properties. We prove that if $X$ has a $\sigma$-point-finite
$cn$-network (resp., $ck$-network), then $\mathcal F[X]$ also has a $\sigma$-point-finite $cn$-network (resp., $ck$-network). ![Creative Commons License](https://i.creativecommons.org/l/by/4.0/80x15.png)
