The AIRCAT 1/4" Flex Head Ratchet, No. 811, provides 35 ft-lbs of torque and features a three-position flex head design for easier access in tight quarters. The ratchet has a feather trigger design and patented ergonomically-engineered handle to relieve stress and fatigue on the operator’s hands, wrists, and arms. The 811 is designed with AIRCAT's patented quiet-tuned exhaust which allows discharged air to pass without developing back pressure, thus retaining more power, while significantly reducing noise, the company says.
