The TK-4L provides a tension fixture at one end of the strap. The added aluminum tension fixture results in the ability to apply manual force to the strap and increase the blood loss stoppage capability of the strap. By wrapping and compressing the strap around the extremity, the added compressive force increases the pressure on the limb and reduced the blood flow. The TK-4L has recently been updated with a new elastic strap that is 50% stronger than the TK-4 and an enclosed tension fixture to make application easier and more secure. TK-4 has been deployed by the US Marine Corps, US Special Forces, and numerous law enforcement and emergency services as a quick way to control severe hemorrhaging while minimizing size and weight.

  1. Great Tourniquet review by Zackariah on 3/16/2016

    This is a great tourniquet. Its easy to use and can even be applied to yourself if ever need be. The elastic material is strong and the metal hooks provide for fast application. You can really tell after applying the tourniquet that its reducing blood flow distally in an extremity.
