3" Copper Round Elbows

Printer Friendly Version

The average installation requires two elbows at the top and one at the bottom. If you are connecting your downspout into a drain tile, the elbow at the bottom is not necessary.

The offset is the measurement of two connected elbows. (see below)
The degree of elbow you use is determined by the overhang of your structure.

To determine the overhang, measure the distance between the wall of your building and the back of the outlet. An overhang of 8" will require 2- 72 degree elbows. If your overhang is greater than 8", you will need to insert a piece of downspout between the elbows.

An overhang of less than 8" will require 2- 40 degree elbows. This elbow combination also works when making a transition around a ledge or other protrusion.

You will need to reduce the size of the opening on the elbows and downspout when using either corrugated or smooth options. (see below)

Installation tips:

A downspout & elbow crimper tool will reduce the size of the opening by crimping the edges of the smooth downspout and elbows.

A needle nose pliers may be used to reduce the size of the opening when connecting corrugated elbows and downspout. Take hold of the inside corrugation with the pliers and turn so the corrugation becomes tighter.
