Love this
Size: 9.25”, Color: black-6 pack, Size: 9.25”, Color: black-6 pack
Perfect, sturdy/ stable, great for the price. So easy to hang. So far very stable and holding a decent amount of weight. Perfect for my sons room and all his legos to keep out of baby brothers reach.

Very sturdy and all hardware needed
Size: 9.25”, Color: black-12 pack
These brackets are very sturdy and came with all the hardware needed, including two types of wall anchors if you won’t be going through a stud, and a magnetic level which was very useful. Would recommend.
