Hackamore curb chain
The role of the curb chain is to exert pressure on the horse's mandible to encourage him to bend the angle of the head and neck on bits such as the pelham, bridle, liverpool, etc. The curb chain is an essential accessory on certain types of bits such as: curb bit, pelham, liverpool, snail bit, etc. It can be optional on the pessoa for example. It also allows to adjust the intensity of the bit and its leverage action according to the rider's settings. It is mainly found in chain, but its effect can be softened with the help of a curb chain protector (in rubber, neoprene or leather). The curb chain is also available in nylon, elastic or other materials that can soften or strengthen its intensity.
The hackamore bridle is longer than a bit bridle, it is placed higher and most often has adjustable attachments on both sides.
