ABSTRACT:
A roof panel clip that extends ten feet in length rather than the usual prior art one to two inches, enabling the clip to span the distance between two purlins to support roof panels over these distances. The extended length of the clip enables it to provide greater strength against uplift loads than that which was possible with the older narrower clips and this continuous clip can be installed more quickly than a series of the ususal smaller clips used to cover the same span.
