Abstract: A clamp structure includes a first channel member comprising a first channel closed side along an axis to receive an elongated member along the axis; a first female member adjacent to the first channel member, the first female member pivots about a first female member axis parallel to the axis; a male member mounted along a first male member axis parallel to the axis; a fastener transverse to the first male member axis; and a female threaded structure attached to the fastener, wherein the female threaded structure is partially received within the first female member to clamp the first female member against the elongated member to clamp the elongated member against the first channel closed side.

Abstract: A clamp structure includes a first female member adjacent to a first channel member comprising a first channel closed side along an axis to receive a member along the axis, the first female member pivots about a first female member axis parallel to the axis; a male member mounted along a first male member axis parallel to the axis; a threaded fastener that extends through the male member transverse to the first male member axis; and a first wing nut threaded to the threaded fastener.
