Abstract
A conduit bending plane and bend angle indicator having a clamp mounting, an anti-dog bubble level to indicate the bend of plane, and an angle bubble level to indicate the bend angle. The invention further features a ratchet connection between the anti-dog bubble level and the clamp mounting to enable the anti-dog bubble level to be referenced at level without having to rotate the conduit to level. A second ratchet connection is also provided which allows the angle bubble level to be set plumb so as to accurately indicate the bend angle without having a first level the conduit along its longitudinal axis. Thus, the disclosed invention provides a quick and easy device to indicate the bending plane and bend angle of conduit being bent without requiring additional adjustments to the conduit once the device is mounted to it.
