Goovilla Heavy Duty Floating Shelf Brackets 4 Inch for 2×4” Wood Stud, 4 Pack L Brackets for Shelves or Shelving, Black Coated Metal Shelf Hardware with 160 lb. Load Capacity and Easy Installation

Love these! They are very sturdy and aesthetically pleasing. Would absolutely buy again. They are easy to install, and came with screws, anchors and a small level! All you need is a screwdriver or a drill. They are made well and have good weight capacity. I used it to put up a shelf to keep some plants up there, away from my kittens. And it looks great!

Super sturdy and easy to mount in my catio. The little float really helped. They’re probably over kill for cat shelves but I love the way they look. (Actually they’re invisible) I am sure that they will last a VERY LONG time even with the rain they’ll get. Hardware was quite sufficient though it would’ve been nice to have a few extra screws. The plastic drywall inserts weren’t needed but they cover all bases for mounting variables you. Little pricey but worth it Purfect size and fit for what I needed. I would definitely use them inside if I needed shelves.

Very well made. I have a few solid wood shelves on it and am not worried at all. Very sturdy, thick metal. However, it does come with drywall hardware - which are the good kind, by the way- and I fell for it. Of course it didn't hold up (as I should have guessed). The holes on the product are very close to each other, so by installing the drywall inserts, there was basically no drywall left to actually hold the thing in place. So I ended up with several holes on my drywall after it gave in. Once installed on studs though (as I should have done since the start because my shelves are heavy), it was perfect.

Very sturdy and easy to hang.

They look great and are very sturdy, as mentioned. I bought the 6 inches for my 8-inch tablets, and they are just perfect.
