I'm using it to keep leaves from blocking an outdoor drain. I had to bend some of the "legs" to get them to fit into the drain cover holes because they didn't match up. It took a lot of effort to get them all in but now it's not going anywhere and it's keeping the big oak leaves from interlocking and blocking this drain. Review: Well made but a bit expensive however fits my 90mm stormwater drain with a bit of effort ## Features - Made of 304 stainless steel, built to last and designed to over 10 years, solid and no splash. - Measure the inner size of downspout, simply push them into holes without any tools.
