Snap table. From left to right: Notching station, slitter and eave/valley hemmer.

A snap table is a device used to shear concealed-fastener metal roofing panels including snap-lock and mechanically-seamed profiles. It is a tool employed by metal roofing contractors in the field or by metal companies in a shop setting. It works by removing a notch of each rib, slitting the panel in half between the removed notches and rolling the pan over for an eave or valley hem.
