The AT Hackamore is a cam style mechanical hackamore. It allows for 3 settings: 

• Screw A + B in place will ensure the quickest application of nose pressure.
• Remove A, leaving B, will allow more rein to be drawn before the noseband is in contact. 
• Removing A + B, will allow the noseband to move independently of the shanks, removing nose pressure.

The AT is supplied with a leather back strap and a choice of two nosebands:

• PVC tube – a more concentrated pressure to bring the nose in. 
• Leather – a softer and broader surface area, rewarding a good head carriage.
