HOUSEHOLD ESSENTIALS MD-61 Retractable Clothesline is a compact, 5-line clothesline that extends to 12.22 feet and retracts into a small, wall-mounted plastic case. The plastic case is durable and weather-resistant for indoor and outdoor use. This case should be mounted to solid non-porous flat surfaces and does best in sheltered areas where it is protected from direct weather. For best results, take down the dryer during inclement weather. Plastic clotheslines are easy to clean and strong. Lines will stretch some during initial use; use tightening knob to adjust tension. GUIDE TEMPLATE for mounting provided on box; however, always check and adjust template holes to match the spacing on the back of the plastic case. TIP: Place a piece of painter's tape between the mounting holes on the case, and then use that tape as your spacing template for mounting.
