A Riser clamp is a device used by mechanical building trades to support vertical runs of piping at each floor level. The devices are simply clamped on with friction and then rest at each floor level. Ordinarily, riser clamps are made of carbon steel and individually sized to fit certain pipe sizes. The term "riser" is typically used to refer to vertical runs of pipes, electrical conduit and tubes.
