PROCEDURE Offset Bend before an Obstruction 1. Measure the distance between the connec- tion point and the obstruction. 2. Measure the height of the obstruction. 3. Consult an off set bend chart or calculator to determine the angle you would like to use for the off set bends. Note the shrink amount and the distance between bends for your chosen angle. 4. Add the shrink amount to the distance you measured in step 1. Measure from the start- ing end of the conduit you will bend and make a mark at this calculated distance. 5. Using the distance between bends found in step 3, mark the conduit back from the fi rst mark. The new mark represents the begin- ning of the fi rst bend. 6. Place the conduit bender handle on the fl oor and secure it in place with your foot. Position the conduit in the bender so that the fi rst mark (beginning of fi rst bend) is aligned with the arrow on the bender head. See Figure 10-10. 7. Bend the conduit to the angle determined in step 3, being careful not to kink it. In this example, the angle is 45°. 8. Without removing the conduit from the bender, rotate the conduit 180° and slide it until the second mark is aligned with the ar- row. Make sure the angled section of conduit is perfectly parallel with the bender handle. 9. Bend the conduit to the angle determined in step 3, being careful not to kink it. 10. Confi rm that the conduit clears the obstruction. Making an Offset Bend (After Measuring and Marking) Step 1. Position the conduit in the bender so that the first mark (beginning of the first bend) is aligned with the arrow. Step 2. Bend the conduit to the desired angle. Step 3. Slide the conduit in the bender, rotate 180°, and align the second mark with the arrow. Step 4. Bend the conduit to the desired angle. Step 5. Install the conduit.
