The Widemouth funnel is designed to eliminate the need for an outlet to connect your gutter to your downpipe. Typical outlets do not have the ability to handle debris, they are not designed for it. Initial thinking in the gutter world was to trap all debris in your gutter and once or twice a year the homeowner would have to clean or pay someone to clean out their gutters. Depending on the are you lived in, the debris could be anything from fine silts and sails to pine needles and heavy leaves. Outlets sit in your gutter, creating a small lip above the gutter line, trapping any dirt and debris making it easy for gutters to become clogged. Widemouth funnels, on the other hand, open up your gutter trough, they allow debris to freely flow from your gutters to the downpipe. This keeps your gutters flowing as freely as possible, the debris would then pass through the downpipe to be caught in your Drainguard, preventing your perimeter drainage from becoming clogged with the debris, or if you did not have perimeter drains, it allows the debris to freely flow on to the ground, for you to clean up with the change of the seasons.
