The patented ratchet handle on the Copper Key lets you work in really tight places where there isn't enough swing room to spin the handle. Just two or three inches of clearance are all you need to prep tubing inside and out. That's not the only twist built into this revolutionary new work saver. The Copper Key is faster, easier, and far more thorough than abrasive cloth. It quickly cleans the outside of the tubing with its patented tungsten carbide coated staples that bite into the tube and strip to a shine in seconds. The staples are offset so that the entire tubing surface will be covered without repositioning the tool. You don't get stripes where the staples missed the copper, as you do with other prep tools. Patented abrasive technology design extends the life of the Copper Key by up to four times that of conventional tools. The memory base allows the staples to spring back after each use and keep optimum pressure on the tube during cleaning. Ever get a scrape or flux burn as a result of prepping copper. That kind of injury is history when you're working with the Copper Key, because your hands stay clear of the brush. The ratchet handle also reduces muscle strain and tiresome wrist twisting.
