We wanted to replace our awful white wire shelving in our pantry and purchased these brackets. Had the wood shelves cut to fit so very easy to install the shelving on top. The lip at the end of the bracket holds the shelf so the brackets do not need to be attached to the shelf. The brackets are very sturdy, heavy metal so they definitely hold the wood shelves and pantry items. Only complaint -the screws that are included. Some of the screws stripped or broke while trying to attach the brackets to the wall studs. They do include an extra screw in each box I guess for this purpose but we still had to purchase additional screws to replace the broken ones. Very frustrating but the finished result looks great and the brackets were an easy fix to replace the old shelving.

Sent more screws when needed!

Screw heads frequently stripped, and on 3 the head sheared clear off. All this despite drilling pilot holes and lubricating screws. The seller was wonderful though and sent extra screws at no extra cost. Looks great and holds well now that complete!

White isn’t Right

The product itself seems to be a good quality, and I did like the design but couldn’t rate it very high based on the white not at all being the right color. It was like a light purply gray ..: especially up against a white wall it was very prominently wrong.

Nice and Elegant.

Color looks great, material is good quality and fits most of my items. It makes my items look neat and organized. Price is a bit high but worth it in my opinion.
