The Iron Sling locks together a force ax and a halligan tool. This perfectly balanced sling lets you carry both tools hands free. Climbing and moving is now faster and safer. The Iron Sling does this by securing the ends of the tools. The shoulder sling is adjustable and fits all firefighters. A quick release heavy duty carabineer on the sling also allows for easy removal. Now newly redesigned for even more safety, the Iron Sling now comes with an axe blade sheath. The sheath is made from heavy duty nylon webbing and can be quickly removed and attached. The Iron Sling is another quality product from the innovative people at Milwaukee Strap Inc. This strap weighs 5 oz.
