Your ideal bender has engineered features which include: Web this will only work on 1⁄2” or 3⁄4” pvc and only for small bends, but it is fast and pretty accurate. The cosecant of angle is the bend multiplier. Web there are shortcuts for a lot of the constants like shrink or multiplier that can be done on a calculator. Web what is the conduit shrinkage—that is, the amount by which the center of the bend will be closer to the end of the conduit than the measured length of pipe? Add the “shrink amount” from the table on page 5 to Remember to ignore the shrink when working away from the obstruction, but be sure to consider it when working into it. Frequently asked questions (faqs) q: Measure the distance from the last coupling to the obstruction.

Frequently asked questions (faqs) q: Web one of the more common bends made in electrical conduit is the offset bend. Why is it essential to calculate conduit shrinkage? The national electric code (nec) specifies a minimum radius for conduit bends in order to avoid damage to both the conduit and conductors. Measure length (l) from end of conduit to offset and add shrinkage (see table 3). Klein tools has provided the correct stub height on each bender head. The first bend should be made at (c), put (star) or b at (c). Web what is the conduit shrinkage—that is, the amount by which the center of the bend will be closer to the end of the conduit than the measured length of pipe? Web measure the distance to obstruction (l) and add shrink amount (chart below) for each inch of offset. Mark the distance on the conduit (x).
