Curb chain

A chain connects the chin protrudes from the horse's mouth both ends of the teeth under the chin groove of the horse together.

In dentures with suits by the Zügelzug is transmitted via the bite suits on the piece and so on tongue and loading of the horse. Curb chains must be of sufficient width and lie flat against the jaw of the horse, otherwise they are banned as animal cruelty because the Zügelzug would be sufficient depending on the length of the suits and width of the chain to break the jaw of the horse. Cases made ​​of rubber or leather can make the pressure on the chin groove evenly, but do not reduce the total existing crushing, crushing effect between the mouthpiece and chain. A milder effect have chin strap of leather or cord, but which do not allow as precise exposure for this reason and need to be replaced more often due to drawdown.
