摘要

The roller shutter end flange (20), designed to fit inside an inverted trough-shaped housing and support one end of the shutter shaft, consists of a main wall (21) and a lower foot (22) shaped to receive an extension bar (53) which modifies its width. The foot (22) can be made to be detachable from or in one piece with the flange, which has a central support zone for the roller shutter shaft. The flange is designed to fit into one end of an inverted trough-shaped housing made from terra cotta, concrete, metal or plastic.
