180° Rotating Arms: The horizontal bars can swing independently. This allows you to fan out wet towels for better airflow and faster drying, or push them flat against the wall when they are not in use to save space. Integrated Hooks: The rack often features built-in hooks at the bottom or sliding clips on the bars (like the ones holding the loofah and brush in your image) for hanging smaller accessories. Damage-Free Installation: Most models use a punch-free adhesive mounting system, which is ideal for smooth surfaces like tile, glass, or marble as it doesn't require drilling holes.
