So you are installing the downspout pipe and you have to jump over that brick (or similar) ledge. Do not worry we have you covered with this 2 piece Style A Ledge Jumper. The offset is about 3 inches for a 2x3 and 4 inches for a 3x4 which are pretty normal requests (if your ledge is different we CAN special order what ever depth and length you need - not cheap but American Made!)
This is Style A. With the widest part against the wall the leg will come at you off the wall. This is a 2 piece configuration allowing you a bit of flexiblity as you put your downpipe into place over that ledge.
Average height for the 2x3" is 14" and the 3x4" is 16"
