The 2432 Gag Bit is increases control by applying pressure to the poll and corners of the mouth when the reins are engaged. The single-jointed stainless steel mouthpiece acts mainly on the bars while providing tongue relief, making it suitable for stronger or forward-going horses.
Size guide
If you already have a bit that fits your horse well, you can use it as a reference for choosing the correct size.
If not, measure your horse’s mouth width by placing a bit sizer or a soft cord/string in the mouth at the position where the bit will sit, mark the ends, then measure the distance. The bit width should be such that the rings rest just outside (or very slightly beyond) the lip corners—if the bit is too narrow, it will pinch; too wide, it will shift side to side. For loose ring bits, allow a little “play” (1cm on one side) so the rings can rotate freely without pinching the lips.
