Abstract
A guide member for a coiling door or curtain assembly, including a rigid, hollow elongate member having a first wall, a second wall opposing the first wall, and a third wall which is perpendicular to the first and second walls. The first, second, and third walls are arranged to form an internal cavity of the elongate member. The internal cavity has an opening running in a direction of a length of the elongate member, along a side of the elongate member opposing the third wall. A seal is positioned in the internal cavity and attached to the second wall. The first and/or second walls have a stepped portion at the opening of the internal cavity which decreases a width of the opening by decreasing a distance between the first and second walls near the opening.
