Versatile and Sturdy
Size: 2 Tier,5.5''Wx10.5''Dx9.5''H
I was able to store a lot of spices in a small space with a couple of these. While you can screw them into the cabinet, I set them on a nonskid shelf liner and so far, don't need to permanently install them with hardware. They're adjustable and sturdy.
