A windlass tourniquet is a limb tourniquet designed for controlling severe external bleeding in an emergency, applied and tightened by rotating and locking the windlass rod. They are standard inclusions in trauma packs, workplace first aid kits, vehicle kits, outdoor bags and range bags.We stock two CAT-style options: the CAT-Style Windlass Tourniquet – Gen 7 Compatible and the CAT-Style Windlass Tourniquet – Gen 6 Compatible. Both follow the familiar windlass-and-strap pattern, so if your service or workplace has standardised on one generation for training purposes, you can order to match.Tourniquet application is a trained skill. These are intended for people who have been shown how and when to use one, and every kit is better for having a practice unit kept separate from the sealed operational one. You will find them alongside our bandages, dressings and wound care supplies.
