stand the amount of sag in the bridle leg
is determined by four factors: the length
of the leg, the weight per foot of the material (usually wire rope) that the leg is
made from, the amount of tension on the
leg, and the angle of the cord. In many
instances, the simple weightless method

not. Our free tool/spreadsheet allows rig-

gers to easily use a more accurate method of calculating the length of bridle legs,
as well as the tension on those legs.
