ABSTRACT:
A roll-up garage closure device of flexible material such as insect screen which is rolled up on a tubular motor driven cylindrical, finned, aluminum roll drum supported by bearings on each end. The screen is attached to the roll drum within a groove formed between two adjacent fins while opposite vertical edges are hemmed over bead chain cording, captured by vertical tracks, and adapted to slide vertically up and down as the screen is rolled up on the drum. A crossbar, containing a semi-rigid guide, two steel bar weights, and a weather seal is attached to the bottom edge of the screen and pulls the screen down as the motor unrolls the screen.
