Using the Greenlee FTXSS-125 fish tape is easy. First, set the case on the ground to free up both your hands. Then, start pulling the tape through the space where you need to install cables. Thanks to the free-spinning interior reel, it should slide out smoothly. When you're done, use the storage lock to keep the tape secure during transport. For maintenance, open the easy-open case to clean the tape or change the quick-change reel cartridge. Remember, the tape has laser-etched measurement markings, so you can measure and fish in one step. It's suitable for general use and can also be used in wet or corrosive environments. Just make sure to dry it off if it gets wet to prevent corrosion. And if you need a replacement tape, you can easily find a compatible Greenlee 125-foot REEL-X™ reel cartridge made of stainless steel.
