3″ x .019 Aluminum Smooth Round & Corrugated Elbows


Smooth elbows will have one end expanded for ease of installation.  

Our Aluminum Elbows are available in several Standard Colors (smooth and corrugated styles) and Select Colors in smooth style. See Color Chart below. We can also produce Select Color corrugated elbows for a $100.00 up charge per order.

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; 40 degree elbows have a 2″–7″ offset and 72 degree elbows have an 8″ offset.

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 9″ will require 2- 72 degree elbows. If your overhang is greater than 9″ you’ll need to insert a piece of downspout between the elbows.

An overhang of less than 9″ will require (2) 40 degree elbows. This elbow combination also works when making a transition around a ledge or other protrusions.

You’ll need to reduce the size of the opening on the elbows and downspout when using either corrugated or smooth options. (see Product Description below left and our Elbow & Downspout Crimper Tool.)

Note: Smooth elbows will have folds in the bend. $100.00 up charge to make select color corrugated downspout and elbows. (Up charge per color)

Note: There is a $100.00 up charge (per color) to manufacture Select Color Corrugated elbows and downspout.

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

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.
