The all new No-Main Curtain is the lowest maintenance curtain on the market and operates without the use of a main cable. The No-Main system is very popular with farmers with large sidewall openings and long barns. Curtain systems can be arranged in a number of different configurations, catering to a wide variety of building and ventilation setups.
With this design the curtain is permanently fastened along the top of the opening. There is a center horizontal sleeve and in the sleeve is an automatic tubular actuator that rolls while travelling up, wrapping the curtain around the centre sleeve as it travels. The system is kept taut and can be locked down in winter months.
