Product review (2 stars): You can make it work.
I used this kit to side vent LG DLGX3571. The straight pipe that directs the ventilation to the side comes up short and does not stick out of the side hole. The reason for this shortage is not the pipe itself being too short but the connection to the elbow is not snug enough, so you need to push the straight piece further into the elbow than it was designed to be, which causes the side pipe to come up short. There is an easy solution to this, if you don't mind the side pipe sticking a little too much out of the hole. I used the pipe that comes with the dryer in place of the "short" straight pipe. The pipe that you remove from the machine (the rear venting pipe) is a good bit longer and does the job well. Overall, I am satisfied with the end result but if I'm paying $80 for 4 pieces of cheap metal, I expect all of those 4 pieces to be up to spec. Hence, two stars.
