Abstract

A clip for electrically bonding a pair of adjacently-disposed metal panels is disclosed. One embodiment entails such a clip (104) including a first clip member (112) and an oppositely disposed second clip member (116). The surface (114) of the first clip member (112) that faces the second clip member (116) includes at least one grounding projection (128), while the surface (118) of the second clip member (116) that faces the first clip member (112) also includes at least one grounding projection (128). The clip (104) may be installed on a standing seam (102) of a panel assembly (100), with its first clip member (112) engaging one of the metal panels 82″ that define this stand seam (102) and with its second clip member (116) engaging the other of the metal panels 82″ that define this same standing seam (102).
