Using the Deltana 12 - foot Surface Bolt is easy. First, find a good spot on the inside of your door to mount it. Make sure it's level. Attach the bolt and the matching strike according to the included instructions. When you want to secure the door, slide the bolt into the strike. Remember, this bolt is made of solid brass, so it's strong but can get scratched if you're too rough. Avoid using abrasive cleaners. To keep it looking great, just wipe it down with a soft cloth now and then. If you notice any loose parts, tighten them up right away. This way, your bolt will work well and look good for a long time.
