The SaHoMa®-II fastening strap is used to attach the SaHoMa®-II housing to the horse's head. The buckles connect to the case once the neck strap is placed on the horse's head. This is simply placed over the horse's halter. For optimal comfort, the neck strap is equipped with removable padding. There are buckles on one side and on the chin for lengthening or shortening the respective strap.
