Does a floor-to-ceiling door panel need a straightener?

The judgment is based on the door panel's height-to-thickness ratio and opening method: the taller and thinner the door, the more likely it is to develop a slight bow under everyday humidity changes, and only then is the straightener's effect noticeable. If the door panel itself is thickened or the width is narrower, installation may not be necessary. Recommendations will be given based on door panel parameters during the planning stage.
