Mantella Trading 310 (Pty) Ltd own patent 98/7391 for Roll-A-Wall Ventilation Stoppings. This industry proved stopping system can be erected by a team of four trained people in under two hours.

This modular system holds many advantages to clients by improving rate of construction thus reducing down time due to ventilation problems and less demand on the transport system because of the light weight and bulk of the components.

Other products have been developed to be used in conjunction with Roll-A-Wall Stoppings such as:
