The Whirlpool WPW10671238 drawer slide rail helps support smooth and stable movement of a refrigerator storage drawer. Installed along the drawer and cabinet support points, this rail guides the drawer as it is opened and closed, helping maintain proper alignment during everyday use. A properly functioning slide rail allows the drawer to move with less sticking, shifting, or uneven motion while supporting the weight of stored items. Replacing a bent, worn, damaged, or broken rail can help restore smooth drawer operation and improve access to stored food. This replacement component is designed for select refrigerator models and should be checked for compatibility before installation.
