The 3 hem curtain system is a one piece curtain. The curtains roll on the center pipe and roll up to the top pipe. If the top pipe is at the header the curtain rolls up out of the way at the header.
The 1 piece 3 hem curtain system is typically used in smaller openings or in applications where the curtains tend to be open or closed. Because the first air comes in at the wall height this system sometimes works better for larger animals not as vulnerable to illness from air temperature changes.
The 1 piece 3 hem system operates with a single drive unit in the cage.
The curtain is made to overlap the concrete wall/footer – so it is important that the face of the column post be flush with the face of the wall/footer.
The 1 piece 3 hem curtain openings are generally smaller than 8’ 6” unless there are curtains on both sides of the barn in which case the opening can be a little larger.
