Patent ID: 6948687

Claim:
A clamp for holding a solar collector header on a roof, comprising: a clamp base adapted to overlie said roof; a clamp top adapted to releasably engage said clamp base; said clamp base and clamp top, when releasably engaged to one another, collectively forming a space between them having a size sufficient to capture and retain without gripping said solar collector header so that said solar collector header may move freely as the collector expands and contracts in response expand and contract responsive to temperature fluctuations; said clamp base including a base wall; at least one aperture formed in said base wall; at least one fastening means adapted to extend through said at least one aperture and engage said roof; said clamp top including a top part adapted to overlie said header; said clamp top further including a pedestal disposed at an angle of substantially ninety degrees relative to said top part; and said clamp base having a bottom part adapted to underlie said header; whereby at least one fastening means is adapted to extend through said aperture and engage said roof; whereby said clamp may be positioned at any preselected location along the extent of said header; whereby said at least one fastening means may be secured in an optimal location on said roof; and whereby expansion or contraction of said solar collector header does not place additional stress upon said fastening means or said solar collector header because said clamp captures and retains said solar collector header but allows said solar collector header to expand and contract without constriction.
