Sekisui / Sekisui Tension Pole Hanger TPH2-WOOD Installation Height Range: 200-275cm This item is equivalent to the following product. Please refer to the link for the instruction manual PDF: https://sekisui-jshop.com/products/tph2-wood?srsltid=AfmBOooG2lAlAVRi6FJub48IOc24tCYxK4Ut-8Xq5yJKfiqykmEmDozc Roughly determine the length and temporarily secure with screws (you can see the holes from that time in the image. You can redo it as many times as you like). Then, tighten it by jacking up the bottom. Some of the rubber rings for the hook stoppers are missing due to aging, but these can be substituted with rubber bands, etc. I am selling this due to a move. All parts have been cleaned. I hope you will consider it.
