Rigging Bridle Calculator+ vs RigThis

This application allows you to calculate the length of the legs, the angle between them, and the forces acting on the bridle and the elements of the structure to which it is suspended. Thanks to additional calculators, it is possible to calculate the Apex height and the position of the bridle point, changes in the load on the beam between two points, as well as the forces acting on the cantilever load, breast line horizontal forces, and several other calculations useful in arena fields. The application accepts all units of measurement, both metric and imperial (cm, m, in, ft). Whether you input values in feet or meters, the results will be accurate and consistent with the unit you used.
