Flat bar 20-hole

The holes are spaced evenly enough that I can line up two bars without fighting the alignment, which saves me a ton of fiddling. It's rigid and holds its shape well when I torque a screw in, so the structure feels solid.

The 20 holes give me way more mounting options than the 11-hole bars I used before, so I could finally brace the frame the way I wanted. Metal is sturdy and the edges are clean, no burrs to file down.

The holes line up perfectly with the matching 20-hole bars I already had, so my frame came out dead square on the first try. Metal is stiff enough that it doesn't flex under load, which is exactly what I wanted for a shelf project.
