Final answer:
To calculate the distance to Mark 2 for fabricating a three-bend saddle with a 45° center bend, multiply the height of the obstacle the conduit must clear by 2.6 to find the spacing, and then add the necessary length to reach the height of the obstruction.
Explanation:
To calculate the distance to Mark 2 for a three-bend saddle using a 45° center bend on a 1 1/4-inch RMC, with a multiplier of 2.6, we use the following method. The distance between bends, known as the 'spacing', for a 45° saddle is obtained by multiplying the height of the obstacle by the multiplier. Therefore, if we let H be the height of the obstruction the conduit must clear, the spacing (S) between the bends will be S = H × 2.6.
Since Mark 1 is the first bend, Mark 2 will be the second bend after the conduit has cleared the obstacle. To find the actual distance to Mark 2 on the conduit, we measure from the beginning of the conduit up to Mark 2, taking into account the length of the conduit needed to reach the height of the obstruction before bending.
For example, if the height of the obstruction is 10 inches, the spacing to Mark 2 would be 10 inches × 2.6 = 26 inches from Mark 1. Therefore, the distance from the left end of the conduit coupled to another piece to Mark 2 will include the length to reach the height of the obstruction plus 26 inches. Rounding the final calculated distance to the nearest 1/16 inch ensures accurate measurements for the fabrication of the saddle.
