Carry extinguishers on your back with the shoulder strap or horizontally in one hand with the center strap.

Two 3-inch VELCRO® brand straps rated to hold up to 2700 pounds each hold extinguishers securely in place. A safety strap with D-ring goes up through the hanging bracket found on all cans to provide extra reinforcement. If for some reason the holding straps are torn open, the safety strap keeps the can from falling out.
 

Fits any standard 2.5 gallon up to 20lbs.
