Installation step one is to attach a thumb-size bracket to the wall with two screws. Then slip the short rear attachment onto the bracket until it sets firmly. In case the rod later needs to be removed, that rear attachment can be lifted up from the bracket. If the rod is long enough to justify a center support, the support attaches to the same type of thumb-size bracket. The business end of the rear attachment is threaded so that one of the telescoping rods screws into it securely. The other side is installed the same way, and the rod on that side has a slightly different diameter so that the two rods slide into one another. The written instructions are clear in case any of this is not obvious. The entire piece is made of sturdy metal tubing, feels strong and seems capable of supporting heavy drapery without bending. The dark bronze finish is perfectly smooth. A well made, well designed piece of hardware for a reasonable price.
