Ported Bit

With no joint, the ported snaffle bears some similarity to the mullen mouth. However, the port acts to reduce pressure over the middle of the tongue and hence increase pressure over the bars. This bit is not as mild as a mullen mouth, and is often used as a corrective bit for horses that have learned to get their tongue over a snaffle, since the port makes this more difficult.

Most curb bits have some degree of port, which is to say an elevated curve in the middle of the mouthpiece. The port makes room for the horse’s tongue to rise up when the bit is engaged, thus putting less pressure over the middle of the tongue and more pressure over the bars. Ports vary in shape by how high they are – a low port puts more pressure over the tongue, but has more clearance for the palate, while a high port gives more room to the tongue, but has a greater danger of interfering with the palate.

Most ports seek a compromise between these two effects, although one alternative is the forward angled port, or Conrad curb. Ports also vary in width, with the main consideration being the width of the tongue groove. On average, 34mm (1 1/2 inches) gives maximum tongue clearance, while still allowing the sides of the mouthpiece to lay comfortably on the bars (which are on either side of the tongue groove). Wide port curbs are made for horses that have particularly wide tongue grooves.

Western S-Shank Curb

The S shape on the shanks of this bit contributes to the weight, balance, and leverage when the rider pulls back on the reins. The S actually makes this a more severe bit than a bit with the same length of straight shanks, such as the grazing bit. This bit needs to used carefully to avoid hurting the horse. Theport in the middle of the mouthpiece amplifies the rein aids and provides some relief to the horse’s tongue.
