Review on Organize Your Under Sink Cabinet With FANHAO Pull Out Storage Shelf - 10.43W X 17.32D X 14.56H, Chrome by Matthew Davenport

4-8 screws depending on how you're going to install it; that's it. They don't even need to be pre-drilled. It doesn't get much simpler than that to install something like this organizer securely. This organizer allows you to choose between a left or right mounting and flipping between the two is very easy. The included instructions are clear in how to flip the orientation and it's just a couple moments of work.These shelves extend with ease and in silence. The operation is smooth all the way until the end of travel and the unit by itself slides almost silently. The bearings are also good enough that while I was waiting to install the unit, the shelf extended by itself because the unit was on a slight decline while on my table due to a magazine under one end. The shelf was not locked in place as I had just set the unit down after unboxing it and the shelf slowly extended itself. So a little angle and a little gravity is all it took to extend the unlocked shelf. Those are pretty good bearings in my opinion!
