K-TEC Gutter Supply 3x4x3 Downspout Drainage Adapter — Universal 3 Inch Round Pipe Connector

Overview

The K-TEC Gutter Supply 3x4x3 Downspout Drainage Adapter is engineered to bridge a 3x4 downspout tile to a 3-inch round drain pipe. Constructed from thicker plastic than many alternatives, it gains a sturdy feel that withstands outdoor exposure and helps keep rocks, dirt, and debris from entering underground drainage lines. The design includes a slightly oversized bore for easy slipping over the downspout and into any 3-inch round drain, while a wider collar conceals the pipe end for a clean, professional edge. Available in White, with Black as another color option, this adapter aims to deliver a neat finish without complicating installation.

Finish and alignment

When installed, the adapter creates a tidy transition that sits level with the surrounding ground, helping you achieve a professional look with minimal effort. The combination of a robust profile and a smooth outer edge reduces visible gaps and enhances curb appeal.

• Slightly oversized to ease slipping over a 3x4 downspout and into any 3" round drain pipe.
