Leg Leveler, 4/8/16 Pack Leveling Feet, Heavy Duty Adjustable Furniture Leveler Legs, with Screws, Lock Nuts and Wrench, 2in Adjustable Height, for Furniture, Table, Cabinets, Workbench(16 Pack)

They installed easily, and work as described.

I have a tall crawlspace with an uneven rocky floor. I wanted to put some shelves on it but couldn't quite figure out how. Since these levelers wouldn't mount directly to my metal shelves, I created a frame just larger than the shelve footprint and added a block in each corner (not shown in drawing) for the shelf to rest on. Finally I added the levelers to the frame. In some cases the 2" leveling action wasn't quite enough to get a shelf completely level, so for the remaining shelves I'm going to modify the design somewhat to "pre adjust" prior to adding the levelers.Overall these are solid and I recommend.

Everything about this product is great except for the quality of the screws. For the most part, the screws were fine, but some of them had bad phillips heads and I could not use them. Lucky for me, I had plenty of spare screws lying around.

I used these to install and level a set of lower cabinets in a garage. They were very easy to install and adjust to get all four cabinets level, in spite of the sloping floor. I would definitely buy them again.

Great for when you have unlevel floors in an old home. Made installaing new kitchen cabinets a breeze!
