The Elevators have upper and lower shanks that are of equal length. The cheek pieces attach to the upper shank and the reins attach to the lower shank. When rein pressure is applied, the bit rotates in the mouth and places pressure on the poll as well as on the lips.
It is a popular showjumping and cross country bit as it offers more control and precision. It has a lifting effect and is especially good for showjumping as you can sit the horse more on its hocks and turn tight.
The Elevator and Elevator Plate bits are more severe than the Elevator Baby and Elevator Plate Baby due to the longer shanks.
