Does it work with screw posts?

In general, Chrysmela works well on screw posts. But the threads on the posts may make it difficult to insert Chrysmela, and also may become less rigid and deep over time with the friction against Chrysmela’s precision internal mechanism.

If you find it not an issue, then you would enjoy Chrysmela. In fact, many of our customers have happily upgraded their screw backs to Chrysmela.
