U.S. Aluminum 3REC 2 in x 3 in Rectangle Gutter Outlet

Make downspout connections fast, clean, and leak-resistant. The U.S. Aluminum 3REC outlet transitions from K-style gutters to 2" × 3" rectangular downspouts with a rigid, corrosion-resistant aluminum body that cuts and rivets easily. A smooth interior helps water move without turbulence, reducing drip points and clog-prone edges.
