Patent ID: 8251326

Claim:
A clamp for securing a module to a roof seam, the clamp comprising: a cam receiver comprising: a horizontal component configured to abut the module and a module clamp; a first vertical component extending from a first end of the horizontal component, the vertical component further comprising a flange configured to abut the roof seam; and a second vertical component extending from a second end of the horizontal component, wherein the horizontal component and the first vertical component form a first corner, and the horizontal component and the second vertical component form a second corner; a cam comprising: a first cam component configured to abut the second corner; a threaded cam insert extending from the first cam component; and a second cam component extending from the threaded cam insert, wherein the second cam component is configured to abut the roof seam; and a bolt comprising a threaded component, wherein the bolt extends from the module clamp through the horizontal component of the cam receiver and the threaded component extends to the threaded cam insert of the cam, wherein the bolt is configured to: engage the threaded cam portion of the cam; pull the cam towards the horizontal component until the first cam component abuts the second corner, preventing further movement of the cam towards the horizontal component; and thereby cause the can to rotate toward the cam receiver, and whereby the flange of the vertical component abuts the roof seam, the second cam component abuts the roof seam, and the roof seam abuts the first corner.
