Ittekoi


Ittekoi (行って来い) – a push-pull motion used when installing (in particular) tongue and groove flooring boards. Unlike non-tongue and groove boards, you can’t simply drop the board into place — due to the locking mechanism. In most cases you can first lock the tongue and groove together and then lower the other end down in a diagonal motion. But if the obstacle has a gap larger than the thickness of the board between it and the subfloor, you can first slide the flooring board past the tongue and groove joint and then pull it back, locking it together.
