Using the Greenlee FTXSS-65 fish tape is a straightforward process. First, set the case on the ground to free up both your hands. Then, use the flexible leader with an eyelet at the tape end to start fishing. The free - spinning interior reel allows for faster and easier fishing. When you're done, use the storage lock to keep the fish tape secure during transport. For maintenance, open the easy - open case to clean it regularly. If the tape gets worn out, you can easily replace it with a quick - change reel cartridge. Remember, this tape is made of stainless steel, so it's great for general use and in wet or corrosive environments. But don't exceed its 400 lbs tensile strength to avoid breakage.
