3x4" Rectangular Inlet | 3" Round Outlet | Black or White | Vinyl Drainage Transition
GA Professional 3x4" to 3" Vinyl Downspout Reducer
Turn a 3x4" rectangular downspout into a clean 3" round drain connection without forcing mismatched parts together. This vinyl downspout reducer helps move roof runoff from the gutter system into round drainage pipe, underground drain lines, French drain tie-ins, and exterior water-routing setups.
Size, Color, and Ordering Details
Product: GA Professional 3x4" to 3" Vinyl Downspout Reducer.
Inlet size: 3x4" rectangular downspout connection.
Outlet size: 3" round outlet for round drain pipe connections.

Weight: 0.4 lb.
Best use: underground drainage connections, round pipe transitions, French drain tie-ins, rainwater discharge lines, downspout upgrades, and professional gutter drainage work.
Clean Transition from Downspout to Round Drain Pipe
A rectangular downspout and a round drain line do not naturally fit together. This reducer bridges that connection by converting a 3x4" rectangular downspout into a 3" round outlet, helping water move from the gutter system into the drainage path with a cleaner, more secure fit.
Use it when connecting gutter downspouts to buried drain lines, landscape drainage, round discharge pipe, dry wells, catch basin piping, or water-routing systems that require a rectangular-to-round transition.
Helps Installers Avoid Loose, Sloppy Drain Connections
When the downspout outlet does not match the drain pipe, installers can end up with gaps, leaks, poor alignment, loose fittings, debris-catching edges, and extra field work. This reducer gives the connection the correct shape change, helping the finished drainage setup look cleaner and perform better.
It is a small fitting that saves time where it counts: at the base of the downspout, where water control, fit, and appearance all matter.
Black or White Finish for Cleaner Exterior Matching
Choose black for dark gutter systems, black drain components, modern exteriors, and high-contrast trim packages. Choose white for white downspouts, light trim, and common residential gutter systems.
The right color helps the reducer blend into the system instead of looking like a random part at the bottom of the downspout.

Installation and Drainage Notice
Confirm the 3x4" inlet and 3" round outlet are correct for the downspout and drainage pipe before installation.
All drainage connections should be aligned, secured, and sealed as needed for the system. Poor slope or loose connections can lead to leaks, standing water, overflow, or drainage backup.
Underground drainage should move water away from the foundation and discharge to an approved location.
Use gloves and eye protection when cutting, fastening, sealing, or working around downspouts and drain pipe.
