The Snap-on 4-pc 3/8" Drive Dual 80 Technology Flex Head Ratchet Foam Set, No. 204RT02FR, includes four flex-head ratchets (stubby, standard, long, extra-long) to provide technicians with ample reach and leverage to tackle every job in the shop. The foam organizer allows for visual tool control and ultimate tool protection. Each flexible head provides increased access in tight workspaces with up to 25 percent less ratcheting arc needed to engage the next gear tooth, the company says. The Dual 80 Technology ensures seven teeth are in contact with the gear at all times, and 80 teeth provide a 4.5 degree swing arc. Contaminants won't penetrate the sealed head and the easy-to-clean foam module resists impurities protecting and increasing the durability of this set.
