The Pole Halter (sometimes called a Head Halter) is generally employed when a lugging pole or rein pole is used. The end of the pole is attached to the ring at the side of the halter. This model has three rings - one at each side and one at the centre. The centre ring can be used for fixing a standing martingale/undercheck if one is used. The chain noseband is used to provide more nose pressure to the horse, and is considered to be more severe than a plain cavesson.
