Using 1/2" E.M.T., you need to form a 3-point saddle bend to clear a round obstruction with a diameter of 3 inches 36" from the end of the conduit to the face of the obstruction. What is the calculated measurement to the center of the bend with shrink? What are the measurements from the center of the bend to each of the other bends? What is the amount of "shrink" that must be calculated for each 1 inch of rise for a 4-point saddle bend with 30- degree bends?
