When we unpacked the canvas, we found some small abrasions on the panel. Either the processing is not optimal or the canvas has been to use. Sorry, we have made a dent in the panel by hanging himself. The sheet metal covering the canvas was along twisted in itself, if you can unscrew the screen to the wall is not a problem, but we had to take the canvas min. 4cm stay away from the wall (wg. Images, door frame). Due to the twisting of the plastic fasteners were twisted so that we were finally about 6 cm away from the wall. To hang the canvas we have with [[ASIN: B003RJRU0Y two wheels holders]] attached to the wall (ceiling mount was because the old building not possible). The pulling out and rolling up the screen works well, only the supplied cord for pulling out is a bit short.
