When tube is inserted in opposite way, the notch is positioned incorrectly and the tube is fixed with wrong angle. This results in defective headrest.

By installing  a additional guide pin/block, the notch side must always be on the correct side when installing the tube and cover into the tool. If positioned incorrectly, the operator will not be able to install it into the tool.
