Zig Zag Leg / Offset for a Downspout Diverter or to shift the downpipe - also used at the transition point from the bottom of the gutter toward the wall
So you just installed the Downspout Diverter and now you are trying to get the downspout to line up so it goes down the wall where you had it before. To complete that move you are going to need this zig zag leg.

This is a single piece of aluminum bent to produce the 2, 4 or 6" Offset
The average length is about 14" for the 2x3 and 16" for the 3x4
This is called a Style B. The wide part against the wall and the leg will take you left or right.
