Just about every screen for use at the input of a downspout has a
very fine mesh, perhaps blocking debris as small as 1/8", even though
such small stuff would pass harmlessly through a typical 2x3"
downspout. This causes the screen to clog, preventing the gutters
from draining and causing them to overflow.

It seems a better design would be something like in kitchen sink
drains use: a large cross that blocks only the stuff big enough to
potentially cause a downstream blockage.

Thanks for your comments.

The ones I use are sort of pear shaped and made from wire, not screen.
They catch leaves and pine needles, but not fine silt. You just place
them into the downspout inside the gutter.

Same item, but look at the price difference at these two places

Anyone ever use one of these wedges?


This is cheap enough
