The Bessey K Body is the original parallel clamp, designed for woodworkers who depend on accurate clamping every time they use it, year after year. The Bessey K Body is for woodworkers who believe "almost" parallel is just not good enough.
Look closely at the workings of a K Body. You will see hardened steel, locking set screws, steel guide rollers and steel anchor pins - the visible part of the mechanism that makes the K Body work. There are also precision internal elements that are not visible. All components are critical to the mechanism which was protected by patent for ten years and is at the heart of the accuracy of the K Body. Without any of them, the K Body would simply not stay parallel … and NO other clamp on the market uses this system to ensure parallelism.
