Using the BasinBuddy™ Universal Faucet Nut Wrench is easy. First, identify the nut you need to remove. If it's a metal or PVC lock nut, or a toilet supply nut, this wrench should fit. Place the open side of the wrench body around the connected supply line and position it over the nut. For hard - to - reach areas, attach the included 1/4' to 3/8' drive adapter and use an extension or universal joints. Turn the wrench to loosen and remove the nut. When using this tool, make sure you have a firm grip to avoid slipping. After use, clean the wrench with a dry cloth to keep it in good condition. Store it in a dry place to prevent rusting. Remember, this is a patented tool from Superior Tool, so handle it with care.
