What is another name for bridle strap?

The bridle is a piece of headgear used on horses to help a rider guide the animal. The bridle is the whole piece of equipment. Synonyms for bridle include check, curb, hackamore, halter, leash, rein, and trammels. There are double bridles where the horse has two bits (this is the part that goes into the horses mouth). There are two kinds of straps involved here, the curb strap and the lip strap. The curb strap, also curb chain, runs from one side of the bit to the other and puts pressure on the chin groove when reins are tightened. Lip straps are used on the smaller of the bits. This one prevents the horse from grabbing at the shanks (piece that stabilizes the bit) with its lips.
