To find the travel length of a rolling offset with 1-foot horizontal offset and 1-foot vertical offset using a 45-degree bent fitting:
Square the horizontal and vertical offsets and add them together like so: 1² + 1² = 2.
Evaluate its square root to find the true offset: √2 = 1.41421 ft.
Finally, divide 1.41421 ft by the sine of 45° to get 1.41421 ft/sin (45°) = 2 ft.
