The Rain Chains Direct Modern Loop Rain Chain is pretty solid when it comes to handling heavy rain, but there are a few things to keep in mind. The manufacturer describes it as being made from durable black powder-coated aluminum, which should help it resist rust and hold up well even in nasty weather.
That said, it's really important to make sure it's set up securely at both ends—both where it attaches to the gutter and where it anchors at the bottom. Our research indicates that if the top part isn't fastened properly, it could get stressed out, especially if a bunch of water or ice builds up on it.
And if it's not anchored at the bottom, strong winds might toss it around during a storm.
According to our research, some folks recommend taking extra steps to keep it steady. One person, Jeff Foster, highlighted the need for a reliable anchor to help it stay put during rough weather. Even though the chain is quite tough, its weight can become a problem if ice, from freezing rain for example, starts building up.
Some people think the ice looks pretty cool, but they also warn that it can put extra stress on the chain.
While it generally works well under regular conditions, if you live somewhere with serious storms or winters, it might be wise to keep an eye on it during those times. Some people even suggest taking it down when expecting severe weather to avoid damage.
Also, since it doesn’t come with an anchor as part of the deal, figuring out how you’re going to stabilize it is a good idea to keep it functioning well when heavy rain hits.
All in all, the Rain Chains Direct Modern Loop Rain Chain can handle heavy rain just fine as long as it's properly secured and occasionally checked on, especially in rough weather conditions.
