Repeatability is often the key to woodwork, getting the same size components consistently without change. The Kreg Swing Stop can do just this when using setups with machines such as mitre saw station, router table, or table drill press or even radial arm saw. It is a fixed stop with a red hairline indicator to ensure accurate readings against the measuring tape.
The sturdy made stop fits neatly into the Kreg Top Trak, allowing it to slide into the right position, and make use of the tape measure. The Top Trak is mounted on the top of a fence 63mm (2-1/4") to allow it the ability to move freely laterally, and swing out of the way when not in use.
