These drawers are sturdy and work well. However, I spoke with a customer support agent who said that the drawer could be detached from the lower support.  It cannot.  I chose these because they open nearly all the way, as opposed to 2/3 of the way, but the undetachable bin proved to be a real headache to install. There's not much room to get to the back of deep cabinet and screw the drawer in. I ended up buying right angle drivers and extended length screw bits to reach some of the areas.  What a hassle!!  They are in place now, and work well, even fully loaded with cans, flour, and other heavy pantry items. I will be using a wood drawer that can be separated from the sliding support for the rest of my project. Great quality, but a hassle to install.
