Our take on the 4x4x3 CORR DOWNSPOUT ADAPTER

A plastic adapter that joins a 4x4x3 corrugated metal downspout to a standard gutter outlet. Its job is simple: bridge the corrugated profile to the gutter so runoff goes where it should. It suits anyone replacing a crushed or mismatched fitting on a metal downspout run. Compared with generic sheet-metal adapters, plastic resists denting and is easy to cut or trim to fit, but it is not a structural connector and can crack under heavy impact or ice.

Questions and answers

Will it fit my downspout?
It is made for 4x4x3 corrugated metal downspouts and a standard gutter outlet. Measure your downspout's profile before ordering; a smooth rectangular downspout of another size will not seat.
Does it come with screws or sealant?
No. Plan on gutter sealant and sheet-metal screws or rivets to secure it, as you would with most plastic adapters.
Can I use it on a vinyl or aluminum downspout?
It is intended for corrugated metal downspouts. On smooth vinyl or aluminum, the corrugated profile will not grip and you are better off with a matching smooth adapter.
Will it hold up through winter?
Plastic handles normal weather but can crack if ice builds up inside or if it takes a direct hit. Keep the run clear of debris and ice dams.
Can I cut it to fit?
Yes, plastic trims easily with a utility knife or snips if the opening is slightly off. Trim a little at a time so the fit stays snug.
Where is the 4x4x3 CORR DOWNSPOUT ADAPTER cheapest?
At Instacart, for $5.28, 55% under what the other stores charge, as of our latest check.
