Question: What are the weight weight limits on this shelf.
Document: It is not only a great &#34;shelf&#34; but also classy and very attractive!It seemed a little pricy but it was well worth it.
I hate the nonsense of shelf-less, tall cabinets in kitchen and bath. What the heck are you supposed to store in those things? Could they possibly have been designed by anyone who had ever actually set up housekeeping anywhere?! I bought four of these cabinet organizers for under our bathroom cabinets. Granted, my space has been doubled, but there are other issues. These shelves do not glide out independently; they work as one unit.
Also, shampoo bottles, mouthwash, anything &#34;tall&#34; has a tendency to topple over when you pull out the shelf. Overall, it's sturdy enough and relatively simply to install, but not as smooth sliding as the Rev-A-Shelf brand. It's a bit top-heavy feeling. One other note: MEASURE every cabinet where you are thinking about installation. Just because it fits in one cabinet does NOT mean it will fit in its identical twin next door.
was delighted with both this and the undersink organizers which I purchased together. glides well and is very sturdy. Just what I wanted
This is very sturdy and contains the hardware to be used as one unit or two. I used it as pictured and it functions with ease. Great product - worth the money.
These products are made VERY well. They are heavy gauge metal and very well constructed. They take about 15-20 minutes to install and will last a lifetime. I now have several of the Household Essential cabinet organizers and I could not be happier with them.
These cabinet organizers are extremely high quality with very rugged construction. When measuring your cabinets for ordering them, be very careful to allow a little extra space for variations and particularly if you have a lip at the bottom of the cabinet opening. I had to build these up to have them clear the opening or I would have had to cut down my beautiful custom cabinets.
These are great organizers, after ordering one I ordered more for all my cabinets.Unit is well made not flimsy, slides easy on the rails.Easy installation, just 4 screws on the bottom.
Measure, measure, measure!
Like product. Wish the bigger one was a bit narrower 14.5 means 14.5 that would not fit my 14.5 inch door opening.
Answer: Not sure of the specifications, but these are heavy gauge shelves. As long as the brackets are securely fastened they should be able to easiy handle 15 - 20 lbs.
