Bending the Offset Insert the conduit into the bender with the 38″ mark positioned at the arrow normally used to bend a 90. The bender handle is likely to kick out when bending in this manner. Slowly bend the conduit, keeping pressure as close to the bender as possible. Click to see full answer. Furthermore, how do you bend a rigid conduit 90 degrees?To use the deduct figure, measure the distance to the far edge of the 90 and subtract the deduct figure. If ½” pipe is being bent and the distance is 56″ place a mark on the conduit at 51″; this is where the bender will be placed. Work the bender onto the conduit with the conduit mark at the arrow of the bender.Additionally, what is the multiplier for a 15 degree offset? The errors in distance between bends for a 30 inch high offset varied from 1/16 of an inch for 1/2 inch EMT with a 30 degree offset to 4 inches for 5 inch rigid pipe with a 60 degree offset. Mathematics of the Offset Bend. Degree of Bend in Degrees (Angle) Multiplier Shrinkage Multiplier in inches 45 1.4 3/8 60 1.2 1/2 Besides, how do you bend a saddle in conduit? The steps to making a three bend saddle are: Measure the height of the object to be saddled. Measure the distance from the end of the conduit to be bent to the center of the object to saddle. Place mark on conduit at distance to center of object. Add 3/16″ to the distance for each inch of saddle required. How do you calculate shrink in conduit?To find out where to place the first mark on the conduit, multiply the measured Offset Distance to clear the obstacle by the tables Shrink/Inch that will occur to the conduit after all the bends are made due to that offset distance or: (Offset Distance) X (Shrink/Inch) = Total Shrink.
