On a finished horse, a bosal with a properly balanced heel knot and mecate generally does not require additional support beyond the headstall. If needed, however, additional support can be provided by one or two accessories. The first is a throatlatch known as a fiador. If a fiador is used, a browband is added to hold the fiador to the headstall. Less often, the bosal may be further supported by attaching the nose button to the horse's forelock or the crownpiece of the headstall, using a single thin strap of leather called a forelock hanger.
