ABSTRACT:
A roll-up closure for closing/opening a vertical opening such as a window or door, includes vertically spaced, horizontal slats, the ends of the slats being slidable in vertical guide channels. The lowermost slat carries a catch which is biased outwardly to a position preventing the closure from being raised. The catch can be released to permit raising of the closure, by means of a cable, a manually actuable member, or a mechanically actuable member.
