This is a new shower caddy made by simplehuman. It has 2 adjustable wire-frame shelves … slide them up or down or sideways on the main vertical track to customize your shower supplies by height or use. It has one stationary bottom shelf for soap. There are a couple handy gray plastic parts to hold razors, washcloths, loofas, etc. The caddy features solid and secure support from both the top and bottom so nothing wobbles or swings. It is constructed from rust-proof stainless steel and anodized aluminum. You hook that top part around the shower pipe and the the bottom suction stabilizes the installation. You can see and find examples on the web. To move the shelves up and down you need to pull up the tab with the simplehuman wording on it then position the shelf and lock it down with the tab. The 2 shelves move smoothly from side to side. Approximate measurements are 28” high x 13” wide (about 14” wide including the razor holders). The shelves will hold about a 3.5” diameter bottle. The unit measures about 4.75” from the back of the post to the front of the wire trays. Retail is about $60.
