Using your Deltana 13-inch Colonial Casement Stay Adjuster is easy. First, make sure your casement window is clean and dry. Then, attach the adjuster to the window frame and sash according to the included instructions. To adjust the window position, simply move the window to where you want it and the adjuster will hold it in place. For best results, avoid forcing the window beyond its normal range of motion. When it comes to maintenance, wipe the adjuster with a soft, dry cloth regularly to keep it looking great. If you notice any dirt or grime, you can use a mild soap and water solution. Rinse thoroughly and dry completely. This will help maintain its durability and the beautiful finish. Remember, this adjuster is built to last, but treating it well will ensure it serves you for a long time.
