The CAT® uses a windlass system with free-moving internal band to provide true circumferential pressure to the extremity.  Once tightened, the windlass is locked in place when bleeding has ceased.  A Velcro® strap is then applied to secure windlass during casualty evacuation.

Special Features:

• Quickly controls life threatening extremity bleeding, the leading cause of preventable combat death.
