This high quality, miniature ratchet is the heart of each Chapman Kit. Originally designed for industry, it is now available to every craftsman. The Chapman twenty tooth ratchet is made of stainless steel and has a strength which far exceeds the torque standards set by Military Specifications.
Reverse action is obtained by simply turning the ratchet over.
Extensions can also be stacked together for more length. The CMS-3 adapter is used to tighten the set screw to lock an adapter or another extension into the extension. Chapman versatile adapters are constructed of the highest quality Nickel Molybdenum Alloy Steel and precision made to insure a proper fit. Ball-detents plus stops quickly position and secure each adapter in either the handle or extension. Constructed of the finest materials and packaged into convenient economy priced sets, Chapman Tools are a must for anyone who deals with small to medium size screws, bolts and nuts.
