发明名称 Offset tape measure
摘要 An offset tape measuring tool marked with standard English measurements includes integrated indicia for quick determination of distance between bends for a given offset depth and offset angle when installing conduit. Additional indicia may be included for the measurement of the shrinkage of the conduit with respect to the specified offset depths and angles. The integrated invention may be part of a standard tape measure strip to provide a convenient multi-purpose tool. Although the tool eliminates any external calculations or table reference typically necessary when bending conduit to clear an obstacle, it still provides an optional reference card for unique bends.
