The high-quality plastic body is not only durable but rust-resistant as well. This will help keep your clothesline looking great over the coming years. Hanging linens to dry saves energy and is an alternative that is made possible and more convenient with the addition of this handy tool. No need to re-tighten or untangle after every load of laundry. This clothesline separator will spare you from complicated unknotting and re-tying and give you more time for other household chores. This clothesline separator is super easy to use and install onto your current clothesline. The polypropylene wheels have wide tracks to accommodate most cotton or plastic clotheslines without hassle. To install this tool, simply insert each clothesline through the side opening of the separator and allow both lines to rest onto their respective wheel tracks. While this separator can be used by itself, its full potential is shown in combination with pulley system clotheslines.
