Powerbuilt Professional Technician ratchets are constructed of high-quality Chrome Vanadium (CR-V) steel with a mirror-polished chrome-plated finish and are precision crafted to exceed ANSI standards for quality and performance. The sealed quick-release button blocks dust and debris and makes socket changes quick and easy. The long reach contour handle fits flat in the palm of the hand adding both comfort and leverage and the thin-profile flex head allows you to swivel the ratchet head up to 180 making it easier to reach into those crowded spaces. These ratchets offer the look, feel and performance hard-working techs deserve.
