The Premium Retractaway Retractable Clotheslines can be used indoors or outdoors and are ideal for basement or garage mounting. The premium retractable clotheslines comes in two sizes with the smallest offering 131 feet of drying space with 5 drying lines which is great for medium wash loads. The largest offers 164 feet of drying space making it perfect for large family wash loads. The drying lines easily extend and retract out of sight. Clothesline Post Mounting Options You can mount one or both ends to existing clothesline posts or you can use your own wooden or steel clothesline posts. If you are mounting the clothesline cabinet to your own clothesline posts, you will need a Retractaway Mounting Bar which is sold separately. We also offer clothesline posts that are specially made for the Retractaway clotheslines and include everything needed to install the clothesline. You can add one or two clothesline posts whether you need them to hold the clothesline with a mounting bar or just secure the opposing end. The clothesline posts are designed to be installed in concrete, but a Clothesline Post Ground Socket is an optional accessory that allows you to remove the clothesline post when the clothesline is retracted and not in use, but is not recommended for a "Post to Post" installation. The clothesline post that holds the clothesline should be cemented into the ground to ensure maximum stability so the "Wall to Post" installation is the best option for using the Clothesline Post Ground Socket. If you're installing the clothesline posts on a concrete slab, the plated clothesline posts, as pictured, will make installation a breeze.
