Answer: B. 9 inches

Explanation: The radius of the bend will add extra length to the bent end of your conduit. Taking this into account we subtract a certain amount from our measurement.

If we are using:

½" EMT conduit, subtract 5"

¾" conduit: subtract 6"

1" conduit: subtract 8"

1¼" conduit: subtract 11"

A stub up bend is a 90º bend near the end of the conduit.We place our conduit on the floor and measure from the end of the conduit to the new length we calculated, and mark the conduit at this point. Then align the arrow symbol on the bender up so it points to this mark. Slot the bender onto the conduit making sure that the bender handle is angled toward the end we measured from.
