A bubble type level for determining the orientation of a structure, such as an elongate pipe, that includes several differently oriented bubble vials that are secured within the level body in a manner such that if the bubble vials become broken or otherwise damaged, they can be easily replaced and the level need not be discarded. The bubble type level of the invention also includes a body portion having top and bottom rails that are chamfered in a manner to automatically align the level with the longitudinal axis of the pipe when the level is connected to the side of the pipe. The level further includes a plurality of longitudinally spaced magnets that are connected to the bottom rail of the level and can be used to releasably interconnect the level with a length of ferrous pipe. |
