Product review (1 stars): Very difficult and doesn't fit right; Doesn't fit right for floor vent conversion.
For the price of this kit, which parts from the hardware store is about $15, LG should at least provide an elbow that is the correct size to the  floor vent conversion!!!
You have to work through a 4 1/2" hole and the elbow is too long.  To expect a customer to "cut" the elbow shorter, when there is NO way to measure how much to correctly cut, is absurd.  The instructions stink and have you cut too much.  Beware, now the elbow is too short to fit through the floor hole in the dryer and you have to go buy new parts from the hardware store to get the kit to work or cut the hole in dryer bottom larger - lousy solution.
There is really no justifiable reason LG to provide the correct length of elbow with the kit!!!
Find another solution if you can as this is just a headache!
