Parachute Stoppings

Coned Parachute Stoppings are used to provide an effective temporary vent control, often used for sealing off old stopes and creating temporary vent circuits.

The cone shape of the parachutes is designed to create a better seal in the drive, providing up to a 95% effective seal.
