Product review (5 stars): Good Kit For My Indoor Lint Trap
I bought this to go with my indoor lint filter. It came with plenty of flex pipe for mounting to the lint trap behind the dryer. It also came with two clamps to secure the flex hose to the top of the lint trap and to the back of the dryer. I purchased this instead of one that can be ordered with the lint trap because of the difference in the shipping.

The flex hose seems to be sturdy and I would order again.
