Each load rings comes with a calibration chart showing the relationship between deflection and pounds force for the individual ring. Units are calibrated in lbf every 20 lbs. from 0 to 1,000 lbs. and every 50 lbs. from 1,000 to 11,000 lbs. with adequate deflection to interpolate to 10 lbs., in kg force and kN. Comes with 3/4"-16 female, threaded mount.
