Example 3: 3-Bend Saddle 45° center bend, 2" obstacle
1. Calculate the shrinkage. See the Greenlee Offset Table, Column 3.
(The amount of shrink for a 22-1/2° bend is 3/16" per inch of
obstacle. 3/16" x 2 = 3/8").
2. Measure the distance to the center of the obstruction. Mark with this
distance on the conduit – this is point "A". Add the amount of shrink to
this distance. (Place the mark 15-3/8" from the end of the conduit.)
3. Refer to the Table for 45° Saddles for the locations of Mark B and
Mark C. (Place both marks, Mark B and Mark C, 5 inches from Mark A.)
4. Use the bending sequence as illustrated. Align Mark A with the
notch near the star. Align Marks B and C with the arrow.
