Snap-on's ratchet with Dual 80 Technology has not only garnered awards for being one of the best new tools on the market, but it also has become a big hit with service technicians who realize that it is quite a unique product. The Snap-on Dual 80 Technology ratchet may look like other ratchets but it has an extremely fine-tooth gear with 80 teeth on a surprisingly compact head - just 1-13/16" wide and 1/2" deep.
