Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pair this B elbow with an offset fitting on the wall run: the offset shifts the downspout tight to the wall and the B elbow kicks the discharge away at grade. Orient the corrugated crimp so water flows into the seam, not out of it, and keep the bottom elbow's discharge aimed toward a splash block or drain line. For 4 in. x 5 in. commercial downspouts, note the 26 GA Galvalume Plus option for extra wall thickness.
Downspout fitting edges are sharp; wear cut-resistant gloves and eye protection when handling and cutting metal fittings.
Order the Rainstamp Rectangular B Elbow to turn your downspout discharge away from the foundation.
