At the one percent level, one CLEAROUT grenade delivers enough CS to reach incapacitating level. Recent tests of OC alone have established its effectiveness though no incapacitating concentration has been determined. Since aerosol valves are normally designed to work only in an upright position it was necessary to develop a valve that would work horizontally. Other modifications to the valve were made internally to speed evacuation of the can to under thirty seconds eliminating potential throwback. Features: Pull Top, Tube Installed, Press Lock Down To Ignite, Contains No Explosive, No License Required to Own. 2oz of a 1% CS / 1% OC Mixture
