FlexArm says its new AR-40 articulating torque reaction arm enhances operator ergonomics and improves production quality.  Equally suited for either vertical or horizontal fastening orientations, the AR-40 is completely mechanical, with no external power source required. Occupying a small footprint, it delivers up to 40 ft/lbs of torque reaction through a working range of 4.25 to 27 inches. Tools up to 10-pounds and one to two inches in diameter can be maneuvered with complete freedom of movement without the operator having to support the tool weight. The AR-40 can be mounted onto a table, cart, pedestal or in an overhead configuration.
