Using the Deltana 4-Foot Kickdown Holder is a breeze. First, find the right spot on your door and floor to install it. Once it's properly installed, when you want to keep the door open, simply step on the holder to engage it. It will hold the door at the angle you've set. To close the door, just give the holder a gentle kick to release it. As for maintenance, regularly wipe it down with a soft, dry cloth to keep it looking good. Avoid using harsh chemicals as they can damage the finish. If you notice any loose parts, tighten them up right away to ensure it keeps working well for a long time.
