The gain for a 90-degree bend with a gain factor of 0.43 and a center line radius of 8" is _____. The notch has nothing to do with the multiplier, it would still be 2.6 if the center bend is 45 degrees. On a 3-point saddle the multiplier for spacing bends is based on the outside bends and not the inside bend. If the center is 45 degrees, the two outside bends are 22.5 degrees and the multiplier will be 2.6. Online degree studies are becoming increasingly popular as more and more people are looking for ways to further their education without having to attend a traditional college or university.There are also different standard pipe bend angles ranging from 15% degrees to 180 degrees.

The second outside bend should be a mirror image of the first outside bend. Once again, use your body to add steady pressure onto the end of the conduit to push it down until the bottom lines up with the 22.5-degree mark on the bender head. For a 30-60-30 saddle, make this final bend a 30-degree angle.The height of the stub, or accurate stub, is the distance from the top of the conduit to the bottom of the 90-degree bend. The height of the stub is determined by measuring the length of the conduit from the center to the center. You can also bend a 3-point saddle with a hand bender. For 15-degree bends, multiply the length by 3.9.When you use a bender with indicators and degree markers - like this one from Klein Tools - making a 30, 60, or 90 degree bend is simple. When making off-set, back-to-back, stub-ups or saddle bends, using a bender with a degree scale and multiplier scale helps save you time and energy.
