3 in. x 3 in.Corner Brace, Steel, Zinc Plated (4 Pack)

I used yellow zinc construction screws and it looks really cool with the different colors inside a built-in I'm making out of an old wood panelling wall I put back up. The screws it comes with might be fine for softer wood, but they didn't work as well as the screws that came with the corner braces. The plates are sturdy and if you use masking tape to hold them in place, they're easier to use.

Super handy. These I will use to secure a standing shelf to a upper wall. But also great to enforce corners of furniture that are of a lesser quality to give them better stability.
