Abstract
A C-clamp with integral bubble levels comprising a C-clamp which has a horizontal portion with two generally parallel vertical portions extending perpendicularly from the ends of the horizontal portion. The first vertical portion is formed with a threaded circular aperture with the axis of which is parallel with the horizontal portion. The second of the vertical portions is provided with a planar surface perpendicular to the axis of the aperture. A rod with exterior threads extends through the aperture and is rotatably coupled thereto whereby rotation of the rod will effect its axial movement. The end of the rod between the vertical portions is provided with a planar surface parallel with the planar surface of the first vertical portion. A planar surface is formed on the horizontal portion on the side thereof remote from the vertical portions. A bubble level is removedly secured to the planar surface.
