Why consider it
Adjustable height and width let it fit the garments and section you already have, without drilling.
Where it falls short
An extender is meant for shirts and other lighter short garments—not a packed row of winter coats.
Before ordering
Measure from the existing rod to the floor, then measure your longest short-hang garment on its hanger. Leave room for both rows and check the existing rod support.
