Product review (3 stars): good but incomplete kit
I needed this kit to reconfigure the exhaust path from it's factory routing of straight out the back to "out the right side" on my new LG DLEY1201V Dryer.  It has all the parts you'll need . . . except for one. You will need to go to Home Depot, or Lowes, and get a coupler that will join together two 4" vent pieces. The part was only $4.00 at Lowes. Why will you need it? It seems that only one end of the curved elbow will fit inside one of the straight pieces . . . the other end of the elbow is the same size as either end of the other straight piece thus needs the 4" coupler. Also a plus to using the coupler is that it adds about 2 or 3 inches to the configuration's length . . . which you actually need to clear the side of the dryer with enough length to more easily attach and clamp the remaining ducting to your wall. Once I had this additional piece I easily conjoined the elbow into the final straight piece that goes out the side and rerouting was successfully finished.
