Big Mouth, Wide Mouth Downspout Outlet for clog free gutters

Allow the water in the gutter to drain faster and keep your gutters clog free with a drain outlet that is many times larger then the typical gutter drop outlet. This gutter to downspout water funnel outlet requires only one screw in the front. The back clips to the top of the gutter tray in the back next to the house. There will be NO raised lip inside of the gutter's bottom to restrict the water or debris from entering the downspout. A very low tech idea that solves 2 very important issues - residual water in the gutter and debris that gets caught on the raised lip of the traditional drop outlet.

You paid good money to have those gutters installed and most of the time they are holding back water and debris. Increase the volume of water and the amount of debris that leave what your gutters with this wide mouth downspout outlet funnel.

Once apon a time ago we found a product very similar to this one. It's made of plastic. If you were not very careful when you installed it they cracked. (Click here to see what happens to the plastic ones) When the plastic funnels are installed correctly there are 4 screws poking up into the gutter bottom. Now you have four places for the debris to get caught on as it tries to get past the screws. IF the installer did not use a good sealant the 4 screws rust and then the water drips through the bottom of the gutter tray at those four locations.
