Heavy Duty Steel L Brackets 6"x6"x3" (4 Pieces)

I used these heavy-duty brackets to build a slim, seamless desk without a bulky traditional base. I built the frame from 2x4s, used 4x4s for the legs, and added a butcher block top, with these brackets reinforcing the connection between the legs and frame.
 
They let you keep the structure tucked underneath the desk while still adding support where the legs meet the frame. If you’re trying to build a simple custom desk or workbench with a clean, minimal look, these make the whole setup really easy.
