The SOF® Tourniquet Gen 4 is comprised of high-strength, lightweight alloy components. Machined from a single aircraft-grade aluminum bar stock, the 5.5” windlass features signature conical ends and grip-friendly texture for consistent torque. Its anodized finish minimizes impacts from environmental elements for durability in any scenario.
It is designed to allow the tourniquet to slide over a limb or, if the limb is trapped, the tourniquet can be rapidly disconnected and reconnected around the limb without rethreading the strap.
The Gen 4 still maintains its true 1.5" tourniquet strap, providing a wider compression pattern than most standard tourniquets or tourniquets with a 1" constricting band moving through a 1.5" sleeve. The wider compression pattern results in additional arterial compression and increased patient comfort.
The SOF® Tourniquet Gen 4 is approved for use by the Department of Defense, the Committee on Tactical Combat Casualty Care, and is the tourniquet of choice for the American Red Cross. It is used by everyone from elite military operators around the world, the largest police departments in the country, fire and EMS paramedics on the streets, and civilians in everyday public places just trying to be prepared.
Performance Compression Band
Reinforced polyester webbing maximizes compression during the application process. At a true 1.5" width, the performance material glides through the Rugged Buckle for quick, snag-free operation and minimizes loss of pressure over time after application.
Slack Indicator Wedge
Stitched into the Performance Compression Band below the windlass. The contrasting wedge offers a visual confirmation you have pulled all excess slack from the band. This is a critical step for proper tourniquet application and results in fewer windlass rotations required to reach occlusion.
Rugged Buckle
Engineered to remove excess slack in a single fluid motion. The buckle's shape stabilizes the Performance Compression Band at any angle of engagement. The Rugged Buckle is an advanced, lightweight composite design with superior strength over previous versions.
High-strength Aluminum Windlass
Machined from a single aircraft-grade aluminum bar stock, the 5.5” windlass features signature conical ends and grip-friendly texture for consistent torque. Its anodized finish minimizes impacts from environmental elements for durability in any scenario.
Tourniquet Retention Assistance Clip™ (TRAC)
Conveniently holds the windlass in place until you can secure it into the Tri-Ring Lock™. The Trac provides steady handling during tough applications and enhances control for one-handed movements.
Tri-Ring Lock™
Complete the tourniquet application by securing the windlass into the Tri-Ring Lock. It can easily be manipulated with just one hand and prevents the windlass from shifting during patient movement.
Time tag
A tag for documenting the tourniquet application time.
Each tourniquet is shipped with two UV-resistant black rubber bands for mounting to your individual equipment.
