Aerko International Clear Out Teargas Grenade is a hand held canister that includes a 3 foot flexible vinyl tube with a plastic penetrating tip. A simple push of the button on the activator top will control the amount of spray. This is an excellent solution for tactical situations where you need to extract a potentially violent person from a confined area, such as a card or motel room. Excellent choice for bounty hunters, why take the risk and kick down the door when you can bring them out to you?

So what exactly does the grenade contain? It contains 6oz of military grade OC/CS in a 1%/1% solution That will deliver a fog to incapacitate a large crowd!

The 6oz. units disperses in 28-30 seconds and covers an area approximately 23,000 cubic feet in 60 seconds.
