Abstract: A device for securing non-magnetic sheet material having a thickness of less than about one millimeter. The device includes a first base inferior planar sheet and a second superior planar sheet. The first and second planar sheets have longitudinal dimensions, parallel to a longitudinal axis of a hinge connecting the planar sheets, that vary from each other by less than fifteen percent. The first planar sheet has an aspect ratio of longitudinal dimension to a perpendicular dimension perpendicular thereto, of between 20:1 and 1:1.5 and has at least one essentially linear first planar sheet longitudinal edge parallel to the longitudinal dimension. The second planar sheet has an aspect ratio of longitudinal dimension to perpendicular dimension of from about 40:1 to about 15:1 where the second superior planar sheet aspect ratio is always greater than the first planar sheet aspect ratio and has at least one essentially linear second planar sheet first longitudinal edge parallel to its Longitudinal dimension.
