Umbra’s Sure-LockTension Shower Rod is so easy to install and use because of its unique finials. On the end of both finials is Sure-Lock technology which creates a vacuum seal between the drying rod??s finials and your shower wall, ensuring it stays put after and during installation. Simply turn to lock each end of the shower rod to ensure it stays in place. This sleek tension rod has a contemporary chrome finish and is made of rust-proof aluminum so you never have to worry about it rusting after being exposed to moisture. Surelock shower telescoping rod extends 114-183 cm to fit most common sized bathtubs and showers and holds up to 14kg. To transform you shower into a multifunctional space, pair your tension rod with the Umbra??s Sure-Lock Dry bar for a highly effective clothes-drying and storage system.
