Professional's Choice-Equisential Performance Ported Chain Bit-EQB-400
This bit is excellent for a horse with a soft mouth. The gag cheek provides elevation in the shoulders. All of these bits should be adjusted to fit with one wrinkle in the horses mouth and a loose curb strap to allow 2-3 fingers.
This mouthpiece will provide the horse with some tongue relief and the chain is light on the bars. Effective in lifting the head and shoulders, the chain allows for independent rein action while the port encourages collection.
