Product review (5 stars): Pure genius! This should be standard equipment included with dryers
I have always had problems with the location of my vent. It is near a wall stud and the vent tube always gets bent or damaged when the dryer is slid back. This is the perfect solution. It prevents damage to the vent tubing and also allows for easier and more secure installation.

I did not need tape or clamps to connect the hose to the dryer. This is genius. All dryers should come with one of these.
