Claim:
A riser clamp comprising: a first bar portion having a first curved central section, and a pair of first extensions extending from opposite ends of the first curved central section; a second bar portion having a second curved central section, and a pair of second extensions extending from opposite ends of the second curved central section; and a pair of fasteners joining the bar portions together; wherein the first bar portion has a pair of holes in respective of the first extensions; wherein the second bar portion has a pair of holes in respective of the second extensions; wherein both of the holes in the second extensions are open holes that are in communication with slots that extend to edges of the second extensions, wherein the slots allow shafts of the fasteners to enter the open holes through the slots; wherein a combined length of the first extensions in directions extending away from the first curved section is greater than a distance between the ends of the first curved central section; wherein a combined length of the second extensions in directions extending away from the second curved section is greater than a distance between the ends of the second curved central section; and wherein the first extensions and the second extensions are each planar, with no protrusions extending therefrom perpendicular to planes of the extensions.
