The new Dual Vent Smoke Screening Grenade has been designed to create a thick blanket of smoke as quickly as possible. With a burn time of 30 seconds, twin vent construction coupled with our simple and familiar twist and strike ignition system makes the grenade especially useful for rapid assaults or withdrawls. Twice the number of smoke exit holes simply makes twice the quantity of cool burn smoke in the same amount of time. This design uses a similar vent design as our other smoke grenades to minimises surging, creating a smooth output and also protecting the surrounding environment reducing the risk of fire.
