We need to solve for our distance between bends (hypotenuse).All bets are off if you don't have the right bend radius. I will be using an Ideal 1" EMT bender. It gives 8" for the circumference of a 90 deg bend, which comes out to 5.04" radius. You show (Fig 7b) an Ideal bender as having a radius of 5.25" (inner radius+1-1/8/2 for the centerline radius), but don't identify it (has to be the 1" tool).As an example, to bend 3/4" EMT conduit have a free end height of 8.5", the table indicates to subtract 6" from the 8.5" which leave 2.5" from the end to bend up to make the mark. Tip: Advanced benders can lay a tape measure next to the conduit and perform the bending operations if the bend does not call for high degree of accuracy. 4. If bending at 10 degrees, the conduit will shrink 1/16" for every inch of rise. 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". Example: For a 4" offset height at 30 degrees, place your first mark at the distance from the obstacle then add your shrinkage calculation. 4" multiplied by 1/4" is one inch. Minimum bending radius for 1/2 inch rigid conduit. 4 inches. Maximum number of 90 degree bends allowed between pulls. 4 (360 degrees) A saddle bend counts as how many degrees? Depends on the bends (60 to 180) T/F - The degree of each bend in an offset must be equal. True. Slide the conduit forward to the 63" mark and, after rotating the conduit 180° once more, make the final bend. The saddle is complete; the run of conduit may now cross the obstruction without difficulty. One of the advantages of a 4-point saddle is that it can be broken in the center, using two pieces of conduit to make the complete saddle. 12- Spray Paint: After the completion of the EMT installation and its boxes, we need to identify the conduits and their boxes are related to which system, either lighting, or power, or fire alarm system, and so on. That’s why we will use spray paint with a specific color to a specific system. Usually, we will use the red color for identifying ...A 3-Point Saddle Bend and 4-Point Saddle Bend Guide. This conduit bending guide will address bending both 3-point and 4-point saddles in EMT conduit (they can also be bent in either IMT or rigid …Make the first side bend on the floor to the 22.5- or 30-degree mark, depending on the center angle. Turn the conduit upside down to create the second bend in the air. Unlike a second offset bend, rotate the bender 180 degrees so the second bend returns the conduit to the same plane to complete the saddle bend. 6. In the same column, find the row labeled L2.
