<p>A door e.g. for domestic garages where there is limited headroom comprises a flexible shutter 16 of articulated laths (24) and a pair of shutter guides 14. The guides 14 are of approximately twice the length of the shutter and have a right-angled bend substantially halfway along. An electric motor may drive a roller 18 profiled to correspond with shoulders 22 on each lath to open and close the shutter. <IMAGE></p> |
