Watching one must, however, if you have painted door frame and you do not want them to scratch. Considering the rod firmly on (which is recommended yes), it may happen that the rubber on the ends fully compresses and the metal rim scratched into the door frame. I thank God it noticed early enough and have built me with two boards, two rubber pads and the fuse holders quasi large "washers". Has the further advantage that the pressure on the doorway to a larger area to spread, so that the whole a little holds even better.
