This concave consists of seven rod separator inserts which is a very passive insert; its main function is to separate with as little damage as possible. It would be used in edible bean crops to reduce dockage due to splits or cracks or with dry canola conditions moving the crop residue with as little damage as possible. This insert can be used for crops such as corn or sunflower. Individually replaceable and 180 degrees reversible. Left hand configuration.
