Web conduit shrinkage refers to the shortening that occurs when a conduit is bent or offset. The cosecant of angle is the bend multiplier. Tools & supplies you need. Master bending measurements, calculations, techniques, and troubleshooting common issues with our comprehensive cheat sheet. Ed with stub, offset and outer marks. (2) bend distance, which is the horizontal length of the bend region.

To calculate conduit shrinkage, multiply the offset distance by the shrink per inch value. Add this figure to the center of bend measurement of 1st conduit. Web these shrinkage multiplier values can be calculated using the calculator below by setting the radius to 0 and adjusting the angle. Measure the distance from the last coupling to the obstruction. 15 degrees is 1/8 for every inch, 22.5 is 3/16, 30 is 1/4, 45 is 3/8 and 60 is 1/2. Using the offset height (z) times angle multiplier (chart below) subtract this amount from the. For instance for shrink, divide the bend angle by 7 and round your answer. Klein tools has provided the correct stub height on each bender head. Web determining shrink values for kicked 90s is the same as figuring for offsets. Web multiplier per angle of bend (see table 2) to determine distance between bends.
