# cups (std. length):
Waterflow Index™ 5/5
3121-Medium vs. 3121-XL!
One of the larger cups we've ever made! A larger version of our Square
Cups line of rain chains.
Beautifully clean, straight lines. Made of pure copper.
Individually crafted by hand, each side
is press seamed for superior strength and durability.
To prevent damage in transit and reduce packaging volume, the upper wires are shipped separately from the cups, so some assembly is required -- it takes just a few minutes with no tools. See our Resources page for a video guide: https://rainchains.com/links.html.
Comes with a copper V-hook for easy installation.
Also available: RCR-1 Installation Kit.
