Parallel kicks forward

When a bank of conduits kicks forward, toward a wall square to the run, they can’t all kick the same amount and stay parallel: the conduit on the inside of the kick has to kick more, and the one on the outside less. Give the calculator one conduit’s kick, the reference, and it works out each neighbor’s.

What to measure

  • Kick and Angle: for the reference conduit.
  • Spacing, inside to inside: the gap between neighboring conduits.
  • Reference conduit OD (optional): leave it blank if the reference conduit is the same size as the one selected.

How to bend it

  1. Bend the reference conduit as a kick with a 90 from the marks shown (see the Kick page).
  2. Bend the Outside conduit and the Inside conduit the same way, each to its own Kick at the same angle, with its own Between bends.
  3. Set the 90s Spacing at the 90s apart, center to center. That is wider than the bank’s spacing, because the legs reach the wall on a slant.
  4. For a bigger bank, work outward one conduit at a time, taking each neighbor as the next reference.

Where the numbers come from

c′ = spacing + (reference OD + OD) ÷ 2
The spacing, center to center.
neighbor’s kick = kick ± c′ × (1 ÷ cos(angle) − 1)
Plus for the inside conduit, minus for the outside one. Between bends and shrink are then the Kick screen’s for that kick.
spacing at the 90s = c′ ÷ cos(angle)

If it turns orange or red

Each conduit is colored on its own, as on the Kick screen, and the results show the worst. The outside conduit, with the smallest kick, usually goes first. Its between bends can even come out negative, which means its bends overlap; the calculator shows the number in red rather than hiding it. Use a smaller angle or a bigger kick.
