Just had 6quot; aluminum rain gutters and downspouts installedWould like to attach a flexible downspout extender but the extenders can't fit a 6quot; wide downspoutI need an Y shape adapter with a 6quot; wide single opening that then splits into two 4quot; openings(The flexible extender is a soft vinyl tube that unrolls to its full length of 9 or 12 feet when the rainwater courses through it and then rolls itself back up when the rain stopsThe extender takes the water well away from the house so there's no flooding of the flower beds from the raingutters' downspoutsThe largest diameter extenders can take is a 4quot; downspout.)
Yes there is You may have to get reducers to 4
